About This Manual
Using Hydrogen
Using Hydrogen
The use of hydrogen as a carrier gas or as fuel for certain flame detectors requires the
operator’s strict attention and compliance with special precautions due to the hazards
involved.
Hydrogen is a dangerous gas, particularly in an enclosed area when it reaches a
concentration corresponding to its lower explosion level (4% in volume). When mixed
with air it can create an explosive mixture. An explosion hazard could develop in the
GC oven when hydrogen is used as a carrier gas if oven elements are not perfectly
connected to each other, or if the connection materials are worn out, broken, or
otherwise faulty.
Use the following safety precautions when using hydrogen:
•
Ensure that all hydrogen cylinders comply with the safety requirements for proper
use and storage. All hydrogen cylinders must be equipped with safety valves and
automatic safety systems.
•
Make sure the gas supply is turned completely off when connecting hydrogen
lines.
•
Perform a bubble test to ensure that the hydrogen lines are leak-tight before using
the instrument.
•
Ensure your GC column oven has a ThermoQuest hydrogen sensor. A hydrogen
sensor continuously monitors the hydrogen level in the GC column oven.
If your GC oven does not have a hydrogen sensor already installed, contact your
ThermoQuest sales representative. To comply with instrument safety
requirements, a ThermoQuest CSE or authorized service technician should install
the sensor.
If you plan to use a sensor other than the recommended ThermoQuest sensor, you
must verify its ability to perform the functions listed above before installing it. It
must comply with your local safety regulations, or with the IEC 10101 regulations
if local regulations do not exist.
Using the Hydrogen Sensor
The lower limit of the hydrogen sensor is 0.5% in volume. You should adjust the
detection threshold to 1% in volume, which is 25% of the hydrogen lower limit of
explosion (4% in volume).
In cases where the connections begin to leak or the column breaks, the sensor alerts
the operator. Then it automatically cuts off the gas supply and heating to the active
zones, and sweeps the column oven with forced air ventilation.

Service Manual
Using Hydrogen
About This Manual
If the sensor detects anomalies or leaks during GC operation due to instrument
malfunction, the operator must immediately:
•
close the hydrogen supply
•
switch off the gas chromatograph
•
air out the room
The reliability of the sensor depends on careful maintenance. After the sensor is in
use, you must periodically check its operating performance and calibration as
recommended by the manufacturer. Refer to your hydrogen sensor’s instruction
manual for maintenance guidelines.
WARNING! Never use hydrogen in your TRACE GC 2000 system unless your GC oven has a
hydrogen sensor installed.
NOTE

ThermoQuest CSEs are not authorized to install or repair any instrument using hydrogen as a
carrier gas unless the instrument is equipped with the appropriate sensor.

Gas Control
The arrangement of the pneumatic gas control system depends on the detectors
configured on the base unit. Three possible configurations of the pneumatic
compartment are available:
•
Digital pneumatics
•
Analog pneumatics
•
Mixed pneumatics (analog and digital)
Digital Pneumatics
In GCs equipped with digital pneumatics, carrier and detector gases are controlled
electronically through a series of electronic pneumatic control modules mounted in
the pneumatic compartment. The Digital Pressure Flow Control (DPFC) modules
control the carrier gas flow, and the Detector Gas Flow Control (DGFC) modules
control detector gas flow.
A single DPFC module can alternate the flow of one carrier gas supply between a
split/splitless injector and another (non-split/splitless) injector.
Analog Pneumatics
In GCs equipped with analog pneumatics, detector gases are controlled by a series of
conventional, manually regulated control modules mounted in the pneumatic
compartment. Manual control is also referred to as non-DGFC.
Mixed Pneumatics
In GCs equipped with mixed digital and analog pneumatics, DPFC modules control
carrier gas flow, while conventional, or non-DGFC, modules control detector gases.
The detector gas pneumatic circuits can be configured for up to three detectors at one
time. Each of the three detector gas flows can be regulated separately. You can easily
interchange different detectors.
Carrier Gas Control
Carrier gas control is only available in DPFC format. The DPFC module allows the
digital control of the inlet pressure and carrier gas flow.

Chapter 1.2
Pneumatic Systems
Gas Control
The DPFC module features the following:
•
Constant pressure or constant flow operating modes
•
Programmed pressure or programmed flow operating modes
•
Inlet pressure control (in kPa, psi, or bar) and column flow rate control
(in mL/min)
•
Split flow control (in mL/min)
Column Evaluation
For pressure controlled injectors (split/splitless and on-column), control of the column
flow is indirect. This means that the GC regulates pressure to control the flow of gas
through the column. To do this, the GC relies on a column constant. The column
constant is a measure of the column’s pneumatic resistance. You can use the
TRACE GC 2000’s column evaluation feature to automatically calculate the column
constant.
Leak Check
A leak check involves six stages.
1. Leak testing the gas source to the GC
2. Pressurizing the split/splitless inlet system
3. Pressuring the packed injection
4. Pressurizing the detector base body
5. Automatic leak checking

Helpful Materials: Electronic Leak Detector, Cut-Off Valve PN 405 100 23, Pressure Gauge
PN 408 500 07, 1/8” Tee PN 403 200 42
The TRACE DPFC gas input contains on and off solenoid valves that are in the off
position when the GC power is off. Figure 1.2-1 Leak Test Parts provides a detailed
description for the following instruction.

Figure 1.2-1. Leak Test Parts
First, connect the gas lines to the GC as outlined in the Site Prep and Installation
manual. While the GC power is still off, turn on all gas supply lines to the GC and set
the input pressure to 420 kPa (60 psig). Allow the gas lines to pressurize for several
seconds. Turn off the input gas source and allow the system to set for several minutes.
The pressure should not decrease. If the pressure drops, locate the leak using an
electronic leak detector. If multiple systems are attached to the same gas source, you
will need to isolate each GC system. An easy way to isolate the GC is to install an
Cut-Off valve (PN 405 100 23) and Pressure Gauge (PN 408 500 07) with a 1/8”
input Tee (PN 403 200 42) in the gas line leading to the GC that you are leak testing,
Be sure the pressure gauge is connected in line between the on/off valve and the GC.
Turn on the gas supply and allow the system to pressurize. Turn off the Cut-off valve
and verify the pressure holds. Keep in mind, this only leak checks the plumbing from
the Cut-off valve to the GC.

Stage 2. Pressurizing the split/splitless inlet system
Helpful Materials: Aluminum Plug PN 290 326 55, M4 Capillary Inlet Nut PN 350 324 23
Turn the GC power on and allow the TRACE GC 2000 to perform its initial self-test.
Insert an aluminum plug PN 290 326 55 (pkg. 10 ea.) into the M4 capillary inlet nut
PN 350 324 23. Attach the nut to the capillary inlet and tighten. On the GC front
panel, press the VALVES button (bottom row). Select Inlet valves. Turn the
appropriate injector split valve and the septum purge valve off. Select the appropriate
Right or Left Carrier. Set the mode to constant pressure. Turn on the gas pressure and
set the inlet pressure to the maximum value. The maximum value can be determined
by moving the cursor to the pressure display line and pressing the Info key on the front
panel. Allow the inlet several seconds to pressurize. The display should show the
selected pressure and the actual pressure. Turn the pressure OFF. The actual pressure
should not change more than 14 to 21 kPa (2–3 Psig) in 10 minutes. If the pressure
begins to immediately drop, use an electronic leak tester and check the split and
septum purge vent, the septum and the fittings on the split vent filter for leaks. Check
all fittings around the inlet.
Stage 3. Pressurizing the packed injector
Helpful Materials: Septum PN 313 032 00, Cap PN 350
010 51
Two types of packed injectors exist on the TRACE GC 2000. One is packed with
septum purge and the other is packed without septum purge. Determine which packed
injector is installed on your GC. Turn the GC power on and allow the TRACE GC
2000 to perform its initial self-test. Seal the inlet using Cap PN 350 010 51. Select the
appropriate Right or Left Carrier. If a packed injector with septum purge is being used,
it will be necessary to turn the septum purge valve off. To turn the septum purge valve
off, press the VALVES button (bottom row) on the front panel. Select Inlet valves.
Turn the appropriate injector septum purge valve off. Select the appropriate Left or
Right carrier. Set the mode to constant pressure. Turn on the gas pressure and set the
inlet pressure to the maximum value. The maximum value can be determined by
moving the cursor to the pressure display line and pressing the Info key on the front
panel. Allow the inlet several seconds to pressurize. The display should show the
selected pressure and the actual pressure. Turn the pressure OFF. The actual pressure
should not change more than 14 to 21 kPa (2–3 Psig) in 10 minutes. If the pressure
begins to immediately drop, use an electronic leak tester and check the septum purge
vent, the septum and all fittings around the inlet for leaks.
Stage 4. Pressurizing the on column injector
The on column injector must be sealed using a short section of capillary column
connected to the injector. Insert the column into the injector as described in chapter 13
of the Operating Manual. Insert the other end of the column into a septa. This should
seal the other end of the column. After the column is in place, turn the GC power on
and allow the TRACE GC 2000 to perform its initial self-test. Select the Left Carrier
and set the mode to constant pressure. Turn on the gas pressure and set the inlet

pressure to the maximum value. The maximum value can be determined by moving
the cursor to the pressure display line and pressing the Info key on the front panel.
Allow the inlet several seconds to pressurize. The display should show the selected
pressure and the actual pressure. Turn the pressure OFF. The actual pressure should
not change more than 14 to 21 kPa (2–3 Psig) in 10 minutes. If the pressure begins to
immediately drop, use an electronic leak tester and check the various parts of the inlet
for leaks.
Stage 5. Pressurizing the detector base body
Helpful Materials: Cap PN 350 061 01, M4 Column Nut PN 350 324 23, Aluminum Plug PN 290 326 55,
Blank Detector Jet PN 404 019 00
Turn the GC power on and allow the TRACE GC 2000 to perform its initial self-test.
Set all detector temperatures to ambient and verify the detector base body has cooled
to ambient temperature. Remove the detector from the base body. Seal the top of the
detector base body using cap PN 350 061 01. If the detector base body contains an
FID or NPD jet, it is not necessary to remove the jet. The seal will fit over the jet. If
the base is configured for capillary columns, remove the column and seal the detector
base inlet using a M4 column nut PN 350 324 23 and aluminum plug PN 290 326 55
(pkg. 10 ea.). If the base body is configured for packed columns, insert a septum
PN 313 032 00 into a septum cap PN 350 010 51 and attach it to the detector inlet to
seal the base body input. Turn on one of the detector gases and allow the detector base
to pressurize.
NOTE
It is not necessary to turn on all the detector gases. With the top and bottom of the base body
sealed, all the gas lines will pressurize back to the flow module. The front panel display will
show different pressures for the various detector gases event though only one of the detector
gases is turned on. Once the base body has pressurized, turn the gas that was used to
pressurize the base body off. The actual pressure should not change more than 14 to 21 kPa
(2–3 Psig) in 10 minutes.
The capillary column base body standard outfit contains a blank Detector Jet
PN 404 019 00. Substituting the existing detector jet with this blank jet will allow the
base body column flow path to be sealed. With this blank jet in place and a column
connected between the inlet and the base body, the inlet can be pressurized and the
complete carrier flow path leak tested. Be sure any H2 and makeup supplies connected
to the base body are turned off when this test is made. Allow several minutes for the
system to pressurize before turning off the column flow. If the system is pressurized
and the split/septum purge vents are off, the actual pressure should not change more
than 14 to 21 kPa (2–3 Psig) in 10 minutes.
Stage 6. Automatic leak check
With the TRACE GC 2000 system you can perform an automatic gas leak check.
When you select the GC leak check function the GC measures the column flow with a
true mass flow sensor and compares it to a calculated flow value obtained from the
original column constant to see if the numbers match. If there is a significant
difference between the two values then the instrument detects a gas leak.

Column Oven Overview
Column Oven Overview
The TRACE GC 2000 column oven provides a stable heating environment for the
analytical column. It heats and cools quickly, and efficient air circulation ensures a
high degree of thermal stability.
Opening the oven door activates a safety microswitch, which automatically switches
off the oven heating and the motor for the air circulation fans. The oven is heated by
resistor elements powered by a circuit located within the GC control unit.
The column fittings in the oven depend on whether capillary or packed column
injector and detector base bodies are installed. Auxiliary gas lines, if installed, end in
M8x1 male fittings between the injector and the detector base bodies. The oven
temperature is monitored by a PT 100 platinum wire sensor and controlled by the GC
control unit.
Figure 2.1-1 shows the positions of the left and right detectors on top of the oven and
the fittings inside the oven.

Split/Splitless Injector Overview
Split/Splitless Injector Overview
The Split/Splitless (S/SL) injector, shown in Figure 2.2-1, is optimized for either split
or splitless applications to ensure effective sample transfer into the column,
minimizing heavy component discrimination.
For both split and splitless applications, the sample is injected through a septum into a
glass liner in the vaporization chamber.
The technique used, split or splitless, determines the choice of the glass liner and the
length of the syringe needle employed. You can control the injector temperature from
ambient to 450 °C, although the actual injector temperature you use depends on
solvent choice and thermal stability of the samples.
In GCs with Digital Pressure Flow Control (DPFC), an electronic device controls the
split flow, while the septum purge flow is kept constant by a calibrated flow regulator.
The S/SL injector is also equipped with electronically actuated On/Off valves for split
and septum purge lines.
Volatile components given off by the hot septum can produce ghost peaks in a
chromatogram. The septum purge system can continually purge the septum with a
flow of gas. This prevents the volatile components from the septum from entering the
column. Figure 2.2-2 shows the septum purge system. Figure 2.2-3 shows the
S/SL injector components.

On-Column Injector Overview
On-Column Injector Overview
With On-Column Injectors (OCI), you use a syringe to inject a liquid sample directly
into the capillary column.
The upper part of the injector has a needle guide and a rotary valve. The lower part
attaches to the top of the column oven. The standard on-column injector does not have
a septum.
The on-column injector is shown in Figure 2.2-6.

Service Manual
Chapter 2.2
Injectors
On-Column Injector Overview
Secondary Cooling System
A stream of gas surrounds the area around the column at the point of injection. This
gas is normally compressed air, but for special applications CO2 can be used. The
secondary cooling flow keeps the injection zone at a temperature below the solvent
boiling point, even when the oven runs at a higher temperature. Elevated oven
temperature helps eliminate peak distortion in the chromatogram caused by flooding
effects.1
The secondary cooling system ensures complete and effective sample transfer from
the syringe to the column and improves reproducibility. Secondary cooling activates
only immediately before an injection and remains on after the injection until all of the
injected solvent has vaporized. The secondary cooling time, which is the duration of
secondary cooling during a run, depends on the oven temperature, the volatility of the
solvent, and the amount injected, but is normally in the range of 3–10 seconds. You
program the parameters for secondary cooling in the INLET menu when an on-column
injector is configured.
Primary and secondary cooling systems are shown in Figure 2.2-7.

On-Column Injector Overview
Optional Devices
Several optional devices and special on-column injectors can be used for special
applications or to help automate certain functions.
Auxiliary Purge Line
The optional auxiliary purge line allows the elimination of excess of solvent that could
accumulate due to incorrect injection conditions. It purges the excess solvent to keep it
from entering other parts of the GC system.
Automatic Actuator
The automatic actuator can semi-automate manual injections by automatically
opening the rotary valve when the syringe needle is inserted. When the needle is
removed, the automatic actuator closes the valve and starts the GC.
High Oven Temperature (HOT OC) Device
The HOT OC device allows on-column operation at high initial oven temperatures,
eliminating the need to cool the oven to a lower temperature for the injection.
Chapter 8, High Oven Temperature Cold On-Column Injector, in the
TRACE GC 2000 Operating Manual, describes this device in detail.
Large Volume On-Column Injector (LVOCI)
The LVOCI is a special version of the standard on-column injector that allows large
volume liquid sample analysis with an AS 2000 autosampler. Special software is
required for this injector. Chapter 11, Large Volume On-Column Injector, in the
TRACE GC 2000 Operating Manual, describes the principles and hardware for this
injection technique.

Solvent Vapor Exit Valve
Large volume injection with the HOT OC technique requires an optional Solvent
Vapor Exit (SVE) valve. This valve allows the venting of the solvent vapors formed
during the sample injection. The SVE valve consists of a specially designed,
electronically activated, heated three-way valve.
The valve inlet is connected to a tee-shaped piece that links the desolvation precolumn to the analytical column. The solvent vapors are vented through the main
outlet which is connected to a solvent reservoir. The SVE valve has a high flow
restrictor. This restrictor, a fine capillary tube, is placed in a special support heated by
the valve. This configuration ensures a very small purge rate (around 0.01 mL/min)
when the SVE valve is closed. This prevents back-diffusion of solvent vapors into the
analytical system.

Flame Ionization Detector Overview
Flame Ionization Detector Overview
In the FID, the effluent from the column is mixed with hydrogen and burned in a
stream of air as it emerges from the jet. The jet acts as polarizing electrode while the
metal collar surrounding the flame forms the collecting electrode.
A polarizing voltage is applied across the electrodes from the electrometer unit to
accelerate and collect the ions that are generated during the combustion process of
organic compounds. The resulting ionization current is sensed by an electrometer
amplifier and converted to a suitable output signal.
Figure 2.3-1. Flame Ionization Detector
Jet
The flame jet, mounted on the detector base body for capillary, wide-bore, or packed
columns is suitable for operating temperatures up to 450 °C. It has ceramic insulation.
Selectivity
The FID responds to almost all organic compounds containing a carbon-hydrogen
bond. The detector does not respond, or responds minimally, to a number of
compounds such as permanent gases, oxides of nitrogen, sulfur compounds, ammonia
and water.
Temperature
The FID is heated from the detector base body. It’s exact temperature is not critical. It
only has to be sufficiently high to prevent condensation of the water vapor formed as a
result of the hydrogen combustion of the flame. It cannot be used with a detector base
body temperature of less than 150 °C. The TRACE GC 2000 will not allow flame
ignition to proceed at temperatures less than 150 °C. The base body temperature is
normally set to the upper temperature limit of the column in use.

The fuel and make-up gases used for the FID are:
NOTE
•
Fuel Gas:

•
Make-up Gas: Nitrogen (recommended) or Helium
Make-up gas is not required when a packed column is used.
The recommended ranges of detector gas flow rates tolerated by the FID are:
NOTE
•
Hydrogen:
30–50 mL/min.
•
Air:
300–600 mL/min.
•
Make-up gas: 10–60 mL/min.
Usually the air flow is about 10 times the hydrogen flow to keep the flame lit.
To gain optimum performance from the FID, you should experiment with the
hydrogen flow rate, keeping the carrier and air flows constant, to obtain the maximum
signal intensity for the components of interest.
Table 2.3-2 shows typical FID operating conditions.
For high-sensitivity applications, it is essential to exclude all traces of organic
contamination from the chromatographic system and/or detector gas lines. Such
contamination may create ghost peaks in the chromatogram or, more often, an

Electron Capture Detector Overview
Electron Capture Detector Overview
The ECD has a low-volume ionization chamber and increased contamination
resistance which ensure high sensitivity and reliability. The detector consists mainly
of a stainless steel cylinder housing a 63Ni radioactive source.
The source acts as cathode in the ionization cell while another cylindrical coaxial
electrode acts as an anode (collecting electrode). High temperature resistant insulating
material ensures effective insulation between the two electrodes and the detector body
The detector is heated by a low-voltage resistor controlled by an electronic
thermoregulator.
Figure 2.3-2. Electron Capture Detector
WARNING! The Electron Capture Detector (ECD) contains a 63Ni beta-emitting radioactive source of
370 MBq (10 mCi).
The 63Ni radioisotope, electrically deposited as metal on a nickel foil, is in a cylindrical
source holder made of 6-mm stainless steel. This holder is fixed to the detector body,
also made of stainless steel, to protect it and make it inaccessible from the outside.
The radioisotope is not released by its support at temperatures lower than 450 °C.
This temperature can never be reached by the detector, whose maximum operating
temperature is 400 °C and is protected by a safety device (thermo-resistor regulator
complying with standard DIN 43760) that does not allow overheating to occur.
The normal operation of the detector does not involve any dispersion of solid or
gaseous radioactive material, and therefore the risk of direct or secondary radiation
(Bremsstrahlung) coming from the detector is practically nil.
Service Manual

Chapter 2.3
Detectors
Electron Capture Detector Overview
For no reason should the detector be opened or handled by the operator. Any
maintenance or service operations involving even partial disassembling of the
instrument must be performed ONLY by qualified personnel at the laboratory expressly
authorized by ThermoQuest and specifically licensed to handle radioactive material.
Wipe Test
The ECD, before leaving the factory, is tested for surface contamination by means of a
wipe test (leak test) method. Each detector is provided with a certificate reporting the
results of the values found and the procedure followed.
NOTE
The users of this detector in the United States are required to perform a wipe test on their ECD
at intervals not to exceed 3 years (36 months) following the reported procedure. For other
countries, please refer to the appropriate agency for equivalent requirements.
Carrier and Detector Gases
In the ECD cell, the 63Ni sources releases ϒ particles that collide with the molecules at
an easily ionizable carrier gas (or make-up gas) to produce low energy electrons.
Nitrogen or argon/5–10% methane are the gases generally used.
Argon/methane is recommended when a higher linear range is required or when
contaminants in the carrier gas make a high mobility of electrons necessary to restore
correct operating values. Both gases should be of high purity and must not contain
more than 1–2 ppm of oxygen or water vapor, since their presence would reduce the
concentration of free electrons and, therefore, the probability of capturing them.
The gases normally used with ECD are shown in Table 2.3-4.

Electron Capture Detector Overview
Operating Principle
The ECD operates according to the principle of gas phase absorption by electron
capturing molecules.
The primary electrons emitted by the radioactive source (beta emission) collide with
the molecules of carrier or make-up gas (such as nitrogen) and give rise to an
ionization process with the formation of secondary electrons and positive ions
(Equation 2.3-1).
ϒ * + N2
ϒ + N2+ + e–
2.3-1
By the application of a weak electrical field between the electrodes, the electrons are
rapidly collected at the anode generating a small current (standing current), while the
possibility for heavy positive ions to recombine with electrons is negligible.
When an electron capturing substance passes through the detector cell, the current is
reduced because of the absorption of electrons by this substance according to one of
the following reactions (Equations 2.3-2 and 2.3-3).
e– + AB
AB– + h↑
2.3-2
e– + AB
A· + B–
2.3-3
In Equation 2.3-2, an energized negative molecular ion forms, while in
Equation 2.3-3, after the electron capture, the molecule dissociates (dissociative
capture) generating a free radical A· and a negative ion B–.
The energy freed during the capture in Equation 2.3-2 is the measure of the electron
affinity of the molecule.
The succession of phenomena determining the detector response ends by the
neutralization of the negative ions formed by capture. The detector response is
therefore related to the loss of electrons that occurs by capture in the system in
equilibrium.
The decrease in the electron concentration is converted into an electric signal
proportional to the concentration of solute present.
Molecular Structure and Detector Response
The sensitivity and selectivity of the ECD response are determined by the electron
affinity of the substances entering the detection cell and are affected by the operating
parameters and analytical conditions.
In the case of organic compounds, the electron affinity mainly depends on the
presence of electrophores in the molecular structure, such as halogens, nitro groups,
organometals or diketons.
For halogens the ECD response decreases in the following order:
I > Br > Cl > F
Service Manual
71
Chapter 2.3
Detectors
Electron Capture Detector Overview
The response factor, and therefore selectivity, can vary between 1 and 106 as a
function of the degree of the electron affinity of molecules, as shown in
Table 2.3-5. These values are also affected by temperature that enhances the detector
response for those compounds capturing electrons dissociatively.
Considering the differences in response, you must calibrate the detector before
performing quantitative determinations. To calibrate the detector, you inject standard
mixtures under the same operating conditions used for the samples to be tested. The
detector sensitivity is also affected by carrier and make-up gas flow rates, since the
detector response is related to the solute concentration of the gaseous mixture.

Constant Current Operating Mode
The detector control module operates in a constant current pulse-modulated mode.
During pulse application, electrons migrate to the anode, and therefore their
concentration in the cell rapidly drops to zero.
During the interval between pulses, electrons gradually return to their original
concentration and to thermal equilibrium in which the capturing process is favorable.
In the relatively long interval between two short pulses, all electrons not consumed by
capture are collected at the anode that measures the electron flow (cell current) present
at that moment.
72
Service Manual
Chapter 2.3
Detectors
Electron Capture Detector Overview
In Equation 2.3-4, the average cell current I is proportional to the concentration of
electrons [e–] collected at each pulse, and to the frequency f of the applied pulses:
I = K[e–]f
2.3-4
In constant current operating mode, the cell current is forced to be constant, at a preset
reference value, through an electric feedback loop circuit that compares the cell
current to the reference current at any time.
When an electron capturing compound enters the detector cell, the electron
concentration [e–] decreases and, according to Equation 2.3-4, the pulse frequency,
required to collect the remaining free electrons, rises to maintain a constant cell
current.
The difference in the frequency when an electron capturing compound enters the cell
and the base frequency, when no sample is present, is converted into an electric signal
which is proportional to the concentration of the compound in the detector.
Base Frequency
Base frequency is an important parameter in evaluating the operating status of the
ECD system.
For a constant concentration of thermal electrons inside the detector cell, the base
frequency is a function of the reference current, pulse amplitude and pulse width
selected. The frequency increases when the reference current is increased, or when the
pulse duration or pulse amplitude are reduced.
For a given reference current, pulse duration, and amplitude, the base frequency
remains constant when only carrier gas and make-up gas flow through the cell. The
frequency generally increases, under the same operating conditions, because of
decreased electron population inside the cell or reduced electron collecting efficiency.
In the latter case, the collecting efficiency can be restored by cleaning or replacing the
collecting electrode (anode).
If the electron concentration has decreased due to contaminants entering the detector
cell, you must remove the source of contamination.
With a high base frequency, probability of electron capture tends to decrease, and
therefore the signal to noise ratio generally decreases.
You must select the appropriate reference current values to maintain the base
frequency at acceptable levels in the DETECTOR (ECD) menu.

Nitrogen Phosphorous Detector Overview
Nitrogen Phosphorous Detector Overview
The NPD provides selective detection of nitrogen or phosphorous organic compounds.
A ceramic matrix thermionic source, positioned above the jet, is electrically heated in
a dilute hydrogen/air environment to create a hot, chemically reactive gas layer around
the source.
When compounds containing nitrogen or phosphorus atoms impact this hot source,
electronegative decomposition products are formed and ionized by extraction of
electrons from the thermionic source. The negative ions are then collected and
detected through the electrometric amplifier.
A thermionic source with a different surface coating is also available. This source
provides high specificity and sensitivity to certain electronegative molecules when
operating in an inert nitrogen gas environment. This is the Enhanced Nitrogen
Selectivity (ENS) operating mode.
The jet, mounted on the detector base body is suitable for operating temperature up to
450 °C. Figure 2.3-3 shows the NPD.
Figure 2.3-3. Nitrogen Phosphorus Detector
Thermionic Source Lifetime
Source lifetime can vary depending on the individual source, the operating
temperature, and the analytical conditions. The source heating current needs to be just
high enough to produce an active layer around the source itself.
When a readjustment of the source heating current is necessary, the magnitude of the
detector standing current or the response to a standard sample can serve as a guide to
the correct adjustment.

Nitrogen Phosphorous Detector Overview
To prolong the source lifetime, we recommend you turn off the heating current and the
hydrogen flow when the detector is not being used for a prolonged period of time (for
example, overnight or on weekends), or when the carrier gas flow is interrupted.
Bleed from silicone-based stationary phases or residual silanizing reagents (from
derivatization procedures) may contaminate the source surface with silicone dioxide
and reduce the operative lifetime. Also the extended use of halogenated solvents can
adversely affect the source lifetime by the formation of reaction by-products on the
source coating.

AUX DET MODULE
Description
Identifies the type of detector
gas flow module in this location.
Possibilities include AA, AB,
AC, AD, AE1, AE2, AE3. All
gas modules have the capability
for three gas paths: H2, Air, and
Makeup. The module type will
determine which gas paths are
present.
Gas path 1 is the H2 gas path.
Gas path 2 is the Air gas path.
Gas path 3 is the Makeup gas
path.
Troubleshooting
If the module is unplugged or
defective it will read None.
Module coding is as follows:
AA = Option 401. Uses gas
module, path 3 only.
AB = Option 402. Uses gas
paths 1 and 2 without the makeup gas path. The ECD make-up
will use gas path 1. The FPD/
FID use gas path 1 for H2, and
path 2 for Air. The PID uses gas
path 2 for sheath gas, and path 1
for Makeup.
AC = Option 403. Uses gas
paths 1, 2, and 3. The ECD uses
Makeup gas path 3 only. The
FID/FPD use gas path 1 for H2,
and path 2 for Air. The FPD can
not be configured for make-up.
The FID uses gas path 3 for
Makeup. The PID uses gas path
2 for sheath gas, and path 3 for
Makeup.
AD = Option 404. Uses gas path
1, 2, and 3. The ECD uses gas
path 3 only. The FID/FPD uses
gas path 2 for Air, and path 3
for H2. The NPD uses gas path 1
for low flow H2, path 2 for Air,
and path 3 for Makeup.
The AE gas module is used for
auxiliary gases. This module
may be configured with gas
paths 1, 2, or 3. This module
uses a proportional
electronically controlled valve
and pressure sensor. It is
designed to furnish flow to a
flow path containing a fixed or
variable restrictor.

Digital Pressure Flow Control Modules
Digital Pressure Flow Control Modules
Digital Pressure Flow Control (DPFC) modules refer to the TRACE GC 2000 inlet
flow modules. These modules are specifically designed to control carrier gas, either
by means of pressure sensing or actual flow sensing.
DPFC flow modules are available in two pressure ranges:
•
0–250 kPa (0–35 psig)
•
0–700 kPa (0–100 psig)
DPFC Purged Packed Carrier Pneumatic Module
The DPFC purged packed carrier module is identified on the module as
PKD-1100-250 or PKD-1100-700. The GC diagnostics identify this module as PKD.
This configuration supplies carrier gas to the GC inlet and offers septum purge vent
control. It is most commonly used with packed columns, wide-bore (megabore)
columns, and the purged packed injector. For wide-bore columns, it operates in
constant flow through calculated pressure. For packed columns, it operates in true
closed loop flow control. The packed flow module uses a high and low auto range
flow sensor, which sets to the high flow range for closed loop flow control. In inlets
for packed column with septum purge operation, the flow control module supplies the
requested column flow plus 5 cc/min for the septum purge.

DPFC Packed Carrier Pneumatic Module
The DPFC purged packed carrier module is identified on the module as
PKD-1100-250 or PKD-1100-700. The GC diagnostics identify this module as PKD.
The packed column module is the simplest in operation. This type of system is used
for packed columns only, which operate in true constant flow mode. The packed
column module is closed loop flow control design. This means that the module
contains a flow sensor, and directly measures the flow being supplied to the column.
The packed flow module uses a high and low auto range flow sensor, which sets to the
high flow range for closed loop flow control. The packed column module does not
require the column evaluation calculation to adjust column pressures during an
analytical run. The packed column module operates from direct flow sensor readings
in flow-controlled mode.

DPFC On-Column Carrier Pneumatic Module
This DPFC on-column carrier module is identified on the module as OC-1100-250 or
OC-1100-700. The GC diagnostics identify this module as OC.
This configuration is most commonly used with cold on-column injectors. This
module controls column flow by means of pressure feedback. The flow sensor is only
used during column characterization. Column characterization is necessary when used
in this configuration.
DPFC flow modules are available in two pressure ranges:
•
0–250 kPa (0–35 psig)
•
0–700 kPa (0–100 psig)
This module has no septum purge or split vent flow control.

sensor and a pressure sensor. It also has a proportioning valve for split flow, and
ON/OFF valves for split and purge flows. The mass flow sensor measures all flow
moving into the inlet.
Since capillary column flows are traditionally low (0.5–3 mL/min), flow through the
capillary column is controlled by means of pressure. The mass flow sensor feedback is
used to control split flow. Septum purge is maintained at a constant by means of a
fixed flow regulator.
The lowest column pressure that must be maintained to control flow is:

Calibration
NOTE
The DPFC electronic control module is trimless. All components are solid-state. Calibration of
the A/D and D/A is a factory-performed operation requiring specialized test equipment. Any
errors in calibration require the replacement of the DPFC module.
Factory calibration is accomplished by measuring the appropriate parameter with a
reference fixture. Then, the actual result is entered in the software. The module is
calibrated for both pressure and flow.

Detector Gas Flow Control Modules
Detector Gas Flow Control (DGFC) modules are used primarily to control detector
gas flow. Flow control is accomplished by applying pressure to a fixed restrictor. The
GC microprocessor provides pressure control. The flow range of the module is
determined by the fixed restrictor. The pressure sensor gage is accurate to 700 kPa
(100 psig). Recommended inlet pressure is 480 kPa (60 psig). Each module is capable
of controlling three independent gases.

General Description
General Description
The primary requirement for any GC is multiple independent temperature controlled
zones. A GC also needs various input and output signals to synchronize and control
peripheral devices. In the TRACE GC 2000, a Motorola 68332 microprocessor
controls all functions.
NOTE
Throughout this manual, the term microprocessor pertains to the Motorola 68332, unless
otherwise specified.
Figure 5.2-1 shows a generalized block diagram of the TRACE GC 2000 base unit.
Figure 5.2-1. Block Diagram of Base Unit
The base unit contains six PCBs in the main electronic chassis, plus the Power Control
Module (PCM). The main electronic chassis contains the following PCBs:
•
Motherboard
•
Central processing unit
•
Temperature feedback and digital I/0
•
Detector controllers (three boards)
The Power Control Module (PCM) contains an additional PCB. The functional blocks
shown in Figure 5.2-1 are distributed among the PCBs.

Theory of Operations
The Motherboard provides communication between the TRACE GC 2000 PCBs and
external devices.
NOTE
The schematic for the motherboard is labeled backplane. Throughout this manual, the term
motherboard will be used instead of backplane; however, the two terms refer to the same thing.
Most of the temperature control channels use RTDs (PT100) as feedback elements. All
of these signals are routed through the motherboard. Most are connected to the
motherboard in an area near PCB connector J1. Certain detectors require an additional
temperature control channel. These detectors route the signals through the detector
PCB and onto the motherboard. Any time that a temperature channel does not have an
RTD connected, the RTD signal must be shorted to ground. In the connector area near
J1, shorted connectors are installed wherever an open RTD connector exists. For the
detectors, there are jumpers (J6-J8) located adjacent to each of the detector card
connectors (J3–J5). When a detector is installed that requires an additional heater, the
jumper should be positioned on the top two pins. When a detector is installed that does
not require an additional heater, the jumper should be positioned on the bottom two
pins.
Three connectors (J3–J5) on the motherboard are dedicated to detector PCBs. Any
detector card can be installed in any of these three locations. If the detector card is for
a Nitrogen Phosphorous Detector (NPD), then a cable from the optional nitrogen
phosphorous (NP) transformer must be plugged into the appropriate NP power
connector (J35-J37). There are three NP power connectors on the motherboard, one
for each detector card location. These are located at the bottom of the motherboard
adjacent to each detector card location.
One connector (J2) is dedicated to the CPU PCB. One connector (J1) is dedicated to
the Temperature Feedback and Digital I/O (TF & DIO) PCB. See Schematics and
Component Layout.
A set of connectors is provided for ON/OFF control of the various gases when the
DPFC option is not installed. These are located on the right end of the motherboard in
an area labeled VALVE OVEN FTD. Table 5.3-1 indicates the function of each nonDPFC gas ON/OFF control connector.

In the lower right corner of the motherboard is a connection (See the PCB
Motherboard/Backplane Standard [119826] Layout for J48 in the section labeled
On_Col Semi Auto Actuator and/or SPI Isolator Board), for a piggy-back PCB, which
controls the semiautomatic on-column actuator. Two piggy-back boards may be
stacked if the TRACE GC 2000 has two semiautomatic on-column actuators.
Five connectors are positioned on the motherboard to provide control signals to
peripheral devices from the rear panel of the TRACE GC 2000. These connectors are:

Central Processing Unit (CPU)
Theory of Operations
Theory of Operations
The Central Processing Unit (CPU) PCB provides the control for all TRACE GC 2000
functions.
Inside the main microcontroller resides:
•
A Motorola 68332 microprocessor
•
2MB of flash memory
•
750KB of static RAM
If the PCB is not fully populated, the memory amounts will be less.
NOTE
Throughout this manual, the term microprocessor pertains to the Motorola 68332, unless
otherwise specified.
Three programmable logic devices (PLDs) provide most of the miscellaneous logic
required. The decode required for the memory chip-selects is generated in PLD U17.
The decode required for the on-board peripherals is generated by PLD U19.
One 256KB bank of RAM has its power supplied from a battery circuit, so that it will
retain its data when system power is off. The chip-selects for these two ICs are
buffered by U10 and U11.
The microprocessor incorporates a variety of subsystems that enhance its usefulness.
These include the Queued Serial Module (QSM) and the Time Processor Unit (TPU).
The QSM provides up to 16 channels of synchronous serial communication with
peripheral devices. Motorola calls this communication type Serial Peripheral Interface
(SPI). SPI communication is always between a master and a slave. In the TRACE GC
2000 the microprocessor is always the master.
The SPI requires four signals:
•
Serial clock (SCLK)
•
Device select (CS)
•
Two serial data lines
The serial data line carrying data from the master to the slave is labeled Master Out
Slave In (MOSI). The data line for communication in the other direction is Master In
Slave Out (MISO).

Service Manual
Chapter 5.4
Central Processing Unit (CPU)
Theory of Operations
In the TRACE GC 2000, SPI communication is used with all peripheral devices not
located on the CPU PCB. Since there are multiple devices to be serviced, multiple
device select (CS) signals are needed. The microprocessor provides four select lines
(PCS0–PCS3). These four lines are decoded in PLD U19 to provide 16 device select
lines (QSM_CS*0–QSM_CS*15). Table 5.4-1 identifies the device serviced by each
select line.

Not Used—Idle State
The TRACE GC 2000 has three serial channels. The first of these is the Serial
Communication Interface (SCI), which is part of the microprocessor. This channel is
used for driving the display panel. The other two channels are supplied by U22. These
two channels are used for communication with the computer and the autosampler. The
device that provides these two serial channels also provides a parallel port which is
not used in the TRACE GC 2000.
Time information for the TRACE GC 2000 is maintained by a Real Time Clock
(U15). The power for this device is supplied by a battery circuit. Its chip-select is
buffered by U12.

Adjustment Procedures
The TRACE GC 2000 uses the TPU functions for most of the controls required for
temperature control. TPU Channel 15 is an input that receives a clock signal, which is
twice the power line frequency, and is synchronized with the zero crossing of the
power line. The functions of the other 15 TPU channels are listed in Table 5.4-2.

Oven Door Stepper—Step

Oven Door Stepper—Direction
The oven door stepper motor is driven by U21, which receives step and direction
signals from the microprocessor through TPU channels.
In order to minimize RF emissions, the CPU is enclosed in a metal shield. An
auxiliary connector on the PCB will allow future expansion of devices that may
require access to the data and address buses.
Each detector card generates a frequency proportional to the analog voltage output.
This frequency must be counted with a consistent sampling gate time. U19 controls
the sample gate. Its time duration is managed by the software. U20 contains counters
for all three detectors.
Adjustment Procedures
No field adjustments are necessary.

Theory of Operations
The Temperature Feedback and Digital I/O (TF & DIO) PCB provides the
microprocessor with the following information:
•
Temperature of temperature controlled zones
•
Ambient temperature inside the electronics compartment
•
Value of the line voltage
•
State of various digital control inputs
In addition, it provides digital output control for values, timed events, handshake
signals, and other functions.
Figure 5.5-1 shows a more detailed block diagram of the temperature feedback circuit.
Figure 5.5-1. Block Diagram of Temperature Feedback Circuit
Input channels are provided for 10 RTDs (temperature sensors), 2 thermocouples,
ambient temperature, and power line voltage.
The temperature channels are separated into two classes: low priority and high
priority. The high priority channels are those that require the most stable temperature
control or the most frequent temperature monitoring.

Theory of Operations
Figure 5.5-2 shows a more detailed block diagram of the temperature feedback circuit
for a high priority channel.
Figure 5.5-2. Detailed Block Diagram of Temperature Feedback Circuit
The voltage across the RTD is amplified by Al and input into one channel of the A/D.
This signal provides the microprocessor with information about the RTD temperature.
The signal resolution is approximately 0.2 °C/bit on the A/D. The microprocessor uses
a D/A to generate a voltage representing the desired setpoint temperature. The setpoint
and the actual temperature from Al are fed into error amplifier A2. The output of the
error amplifier represents the difference between the desired temperature and the
actual temperature. This signal is presented to a second channel on the A/D with a
resolution of about 0.0025 °C/bit. The low priority channels function the same way,
except the signals are multiplexed instead of having dedicated A/D channels.
The signal names of the temperature controls are listed in Table 5.5-1.

Most of the required binary input and output signals are controlled or monitored
through PLD U42. The signals that control devices external to the PCB are listed in
Table 5.5-2. In addition, U42 provides the control signals for the analog multiplexer.
All of the RTD input channels are monitored with comparator circuits. This allows
checking of the oven temperature conditions. If any channel goes over approximately
525 °C, a signal is generated to the power control module that turns off all heaters. An
open RTD represents a very high temperature. Therefore, all unused RTD channels
must have a jumper in place of the RTD. Some temperature zones are controlled
through the detector cards. If no detector is installed, or if the detector installed does
not have a secondary heater, a jumper must be installed on the motherboard adjacent
to the detector card connector.

Two options for the TRACE GC 2000 require temperature feedback using
thermocouples instead of RTDs. These options are the PTV and the OCHOT.

Service Manual
Chapter 5.5
Temperature Feedback and Digital I/O
Adjustment Procedures
When a thermocouple is required, an additional amplifier circuit is needed. This
circuit is in the form of a “piggyback” PCB which is plugged onto the TF & DIO
PCB. Up to two of these amplifiers may be installed. When installed, they plug on to
connector J1 or J2.
Some of the early assemblies of the TF & DIO PCB included a special circuit which
stabilized the temperature of RN4. The network RN4 was moved onto a special
piggyback PCB and the temperature of RN4 was controlled by the circuitry on the
piggyback PCB.
Adjustment Procedures
The Temperature Feedback and Digital I/O (TF & DIO) card is factory-calibrated with
values stored in EEPROM on the card. No field adjustments are possible.
Schematics and Component Layout
The schematics and component layout information for the Temperature Feedback and
Digital I/O (TF & DIO) PCB is listed below in Table 5.5-3. Also included are the
schematics and component layout information for the Thermocouple Amplifier
piggyback circuit (used for PTV and OCHOT options) and the RN4 Temperature
Stabilizer piggyback circuit (used on some early assemblies). The number of drawings
has been included for each schematic and its corresponding layout. There are 13
drawings for reference in this section.

for all of the heaters.
The dc voltages required by the GC are supplied by a commercial power supply. This
supply provides +5 V, +15 V, –15 V, and +24 V. The +5 V is used by the
microprocessor and the logic circuits. The +15 V and –15 V are used by the analog
circuitry in the basic frame and oven of the GC. The +24 V is used by the detectors to
provide local voltages for the analog circuitry and for driving valves.
A relay in the PCM chassis controls power to all of the heaters. If it is open, no power
is available to any of the heaters. The watchdog signal generated on the Temperature
Feedback and Digital I/O (TF & DIO) PCB triggers a retriggerable one-shot (U13)
that controls the relay. The software must trigger the one-shot several times per second
to maintain power availability to the heater and the inlet cooling fans. The PCM has a
thermal cutout (SW1 on the PCB) that will disable the heater power if the temperature
in the PCM exceeds 55 °C.
Each line voltage heater channel is controlled by a triac interfaced to the
microprocessor with an optocoupler. Each low-voltage heater is controlled by a triac
interfaced to the microprocessor with a transistor.
The PCB in the PCM contains a transformer with two secondary windings. One
winding drives a comparator (U10) that generates a square wave from the line voltage
sine wave. The square wave drives two one-shots (U11) that trigger on opposite edges.
The outputs of the one-shots are combined in the PLD (U3) to create a clock two times
the power line frequency and synchronized to the zero crossing of the power line
voltage.
The second winding of the transformer generates an unregulated DC voltage. This
voltage is proportional to the line voltage and is monitored by the microprocessor.
Circuits are provided to monitor the voltages from the DC power supply. If any supply
is not present, the power available to the heaters is disabled. The status of the DC
supplies is input to the microprocessor through the PLD (U3). In addition, these
signals drive LEDs on the motherboard.
An oven door interlock switch provides an override for the control of the oven heater
and the oven blower. If the door is open, both the heater and the blower are disabled.
Depending on the GC configuration, a combination of up to two out of three possible
transformers may be installed in the PCM.
Transformer 1 (119916) provides voltage for the FID ignitor. This transformer is used
when an FID is present, but there are no requirements for low-voltage heaters.
Transformer 2 (119917) provides voltage for ignitors and low-voltage heaters. This
transformer is used when there is a requirement for low-voltage heaters.

Chapter 5.6
Power Control Module
Adjustment Procedures
Transformers 1 and 2 are mutually exclusive. A pigtail on the transformer leads must
be plugged into J6 on the Power Control PCB to indicate to the microprocessor which
transformer (if any) is present.
Transformer 3 (PN 230 43444) (119917) provides power for the NPDs. It is present
only when the NPD is present. A pigtail on the transformer leads must be plugged into
J4 on the Power Control PCB to indicate that the transformer is present.
The Power Control PCB can be configured for 115- or 230-volt operation. A jumper
on J3 indicates the selected voltage configuration to the microprocessor. Place the
jumper between pins 1 and 2 for 115 V ac or between pins 2 and 3 for 230 V ac. The
jumper assembly on J 12 changes the connections to the transformers and the oven fan
motor. For 115 V ac, position the block with the black lead toward the end near the
transformer on the PCB. For 230 V ac, position the block with the black lead away
from the end near the transformer on the PCB.
WARNING! For conversion from 120 V ac to 230 V ac, all line voltage heaters must be changed. For
European configuration, it is necessary to convert from 230 V ac to 120 V ac. Again, all
line voltage heaters must be changed.
Adjustment Procedures
No field adjustments are necessary.
Schematics and Component Layout
The schematics and component layout information for the Power Control Module
(PCM) PCB is listed below in Table 5.6-1. The number of drawings has been included
for each schematic and its corresponding layout. There are six drawings for reference
in this section.
The Power Supply PCB schematics and component layout are not included in this
manual because the PCB must be replaced as a unit. When ordering a replacement
Power Supply PCB, refer to the part number (PN) in Table 5.6-1.

Theory of Operations
Circuit Function
The Digital Pressure Flow Control (DPFC) PCB is located on the rear of the
Analytical Unit. The DPFC PCB is controlled by SPI (Serial Peripheral Interface)
signals that come from the motherboard through the P6 connector (MOSI, MISO, SS,
OVEN, SCK), and take the +5L, +/–15A, +15P, COMMON (Analog, Digital, Power)
through the P8 connector.
An X1 quartz crystal generates the clock frequency of 8 MHz. The crystal is
connected directly to the local MC68HC11A1 microprocessor (U14, Xtal and Extal)
through the resistor (R11).
NOTE
The DPFC PCB uses an on-board MC68HC11A1 microprocessor. In this section, the term
microprocessor refers specifically to the MC68HC11A1.
The 8-bit single-chip microprocessor 68HC11A1 (U14) includes 512B of EPROM
and 256B of static RAM. This microprocessor controls:
•
EPROM 27C512 memory (U13, 64KB)
•
Data bus (AD0–AD7)
•
Address (A8–A15) bus
Two stages of the integrated circuit 74HCT00 (U19) generate the RESET signal
(active low) to initialize the microprocessor to a known startup state. The
microprocessor provides an E output frequency signal on pin 5 (used as reference
timing). Pin 5 is actually one-fourth of the input frequency of 8 MHz at the Xtal and
Extal pins. Two CNY17/II optocouplers (U4, U5) read the PURG1 and PURG2 input
signals to recognize the presence of the purge line of the split/splitless injectors
controlled by DPFC devices.
Chip-selects (O10–O16, O20–O24) are generated by two 74HCT374 3-State buffers.
The other two stages of the integrated circuit 74HCT00 generate the digital output
signals to select the 74LS138 decoder (U23) and the 27C512 EPROM (U13).
The following connectors control all signals for five DPFC devices:

Digital Pressure Flow Control
Adjustment Procedures
The circuit consists of two TL082 integrated circuits (U17, U21) and the NPC1210.
The purpose of the circuit is to read the ambient pressure.
Integrated circuits 74LS139 (U12) and 74LS04 (U11) generate three enable signals to
select three ADG408 integrated circuits (U2, U6, U8), which read all analog inputs for
DPFC pressure and flow data. The output D of the ADG408 is an analog serial data
output. The microprocessor will digitally read this output (DADY, AMISO, ASCLK,
AMOSI, RES) through the AD7715 (U1).
The voltage regulator 78L05 (U26) supplies the +5 V dc.
Adjustment Procedures
No field adjustments are necessary.

Theory of Operations
Theory of Operations
The keypad and display panel are the primary means by which the user communicates
with the GC.
Drawing 119841 shows the keypad schematic. See Schematics and Component
Layout. One PLD provides control for scanning the display and for driving the status
display LEDs. The microprocessor communicates with the PLD through the SPI bus
several times per second. With each communication, the PLD sends data to the
microprocessor to indicate which key, if any, is pressed. The microprocessor then
interprets this information and takes the appropriate action.
The display receives serial data from the microprocessor’s SCI output and displays it
on the vacuum florescent display.
NOTE
The display is a purchased assembly. It is a non-repairable component. The keypad and display
panel module is designed to be replaced and not repaired.
Adjustment Procedures
No field adjustments are possible.
Schematics and Component Layout
The schematics and component layout information for the keypad and display panel
PCB is listed below in Table 5.8-1. The number of drawings has been included for
each schematic and its corresponding layout. There are two drawings for reference in

Theory of Operations
Theory of Operations
Circuit Function
The main purpose of the Flame Ionization Detector (FID) PCB is to control the IGNIT
(flame igniter coil), –300 V (flame jet polarization), and input (low current produced)
of the FID. The FID PCB takes all digital inputs/outputs (P1 connector) and the power
voltages (+5 V dc, +/–15 V dc, +24 V dc) from the motherboard.
The low-current signal (DET CABLE) produced from the FID is connected to the
input of the 2N5909 preamplifier (U24) by a dedicated cable with coaxial connector.
The output signal then goes to the OP07 amplifier (U25).
There are four J201 FETs (Q8–Q11) to select the range of the input current. The input
current then goes to the first analog input of the amplifier OP77 (U26) on pin 3,
together with the second analog input on pin 2 as a back-off current signal (VBO).
A back-off bucking current is generated from the DAC0801 converter (U18, U19) and
the OP07C amplifier (U23). The LM324 integrated circuit (U22) generates four
signals to select the range input current (PN1–PN4).
Three 74HC595 integrated circuits (U13, U15, U16) generate the output chip-select
(O1–O6) and the background chip-select (Z0–Z15).
Integrated circuit 74HC240 takes the input serial data (CLOCK, MOSI, MISO), the
chip-select (CS), the +5 V dc, and GND from the motherboard.
Custom chip 24SCR4.5D15M (U12) takes the input voltage of +24 V dc to generate
the +/–15 V dc and the +5 V dc through the 78L05 regulator (Q1).
The integrated circuit MOC3020 (U20) takes the input voltage of 8 V dc through the
BTA06 triac to supply the flame igniter coil of the FID (P5). The integrated circuit
MOC3020 (U20) is selected from two signals (O4, O5) generated by 74HC595 (U16).
The electronic circuit includes:
•
BC107–BC177 transistors (Q2–Q7)
•
IN4148 diodes (D3–D13)
•
Capacitors (C12–C45)
The function of the electronic circuit is to generate a negative voltage of –300 V to
polarize the flame jet of the FID. The P2 connector gives 0 V (signal common), 1 V,
10 V, and GND (chassis) outputs to connect an integrator or to handle chromatograph
data externally.

Adjustment Procedures
Calibration Adjustments
Refer to the calibration of potentiometers shown in the F1/4 drawing located in
Schematics and Component Layout.
Special Notes
In order to verify the FID electrometer noise level, follow this technical procedure:
1. Remove the coaxial connectors of the signal cable from the FID
2. Wrap up the coaxial connectors using aluminum foil
3. Connect the analog output signal (0–10 mV) to recorder
4. Set parameters ATT=0 and RNG=0 (max sensitivity)
The noise level must be within 1% of full scale.

Electron Capture Detector Controller

Theory of Operations
Circuit Function
The main purpose of the Electron Capture Detector (ECD) PCB is to control the pulse
frequency (FC1034, J5) of the radioactive source (63Ni) and the input (low current
produced) of the ECD. The ECD PCB takes all digital inputs/outputs (J8 connector)
and the power voltages (+5 V dc, +24 V dc, GND) from the motherboard.
The low-current input signal (FC1033) produced by the ECD is connected to the input
of the 5909 preamplifier (U1, point N1) by a dedicated cable with a coaxial connector.
The output signal then goes to the OP07 amplifier (U11). The 48 V dc output voltage
required to supply the heater elements (thermoregulation) and the input signal of the
PT100 sensor (reading temperature) of the ECD are connected to the female connector
(J9). The analog output signal (V DET) of the operational amplifier OP07 (U12) goes
to the VFC110AP converter circuit (U26) through two OP07 operational amplifiers
(U2, U3).
The output frequency signal (F-OUT) of the VFC110AP (pin 8) goes to the
motherboard through 6N137 (I1) and the J8 connector to be read by the main TRACE
microprocessor. The same V DET signal goes to the TL082 output stage (U4A) and
three resistors (R50, R56, R57) to generate the output voltages of 0–1 V and 0–10 V.
These outputs are used for external connections to:
•
A recorder
•
An integrator
•
A data handling system (ChromCard or ChromQuest)
The circuit for the autozero function consists of the OP200 (U4B) and 4066 (U5A),
which are controlled from the DOING AZ input signal.
The autozero analog signal is generated by:
•
Two 74HC273 integrated circuits (U27, U28)
•
Two DAC0800 converters (U22, U23)
•
OP07 amplifier (U20)
A local MC68HC705 microprocessor (U24) controls the following:

•

•
Address bus
•

Chapter 5.11
Electron Capture Detector Controller
Theory of Operations
The integrated circuits 74HC240 (U29A–B) and four 6N137 (I3–I6) are used to
perform the serial communication with the motherboard through the J8 connector. The
pulse width (0.1µS, 0.5µS, 1µS) of the outpulse frequency (J5 connector) is generated
by four 74LS221 circuits (U8, U13) and the 74LS153.
The circuit consists of:
•
Diodes
•
Resistors
•
Capacitors
•
Transistors (Q3–Q7)
The current circuit consists of:
•
Integrated circuit 74HC273 (U18)
•
Converter DAC0800 (U14)
•
Amplifier OP07 (U9)
The voltage circuit consists of:
•
Integrated circuit 74HC273 (U19)
•
Converter DAC0800 (U15)
•
Amplifier OP07 (U10)
The regulator LM7805 (U31) generates the +5 V dc. Two regulators, LM7815 (U32)
and LM7915 (U33), generate the +/–15 V dc. The J2 connector gives the 0 V (signal
common), 1 V, 10 V, and GND (chassis) outputs to connect an integrator or to handle
chromatograph data externally.
Detector Heat
The Electron Capture detectors require additional heat control for the detector cell.
This heater voltage is furnished from the Power Control PCB on the power control
module. The heater voltage output from the power control PCB is passed through the
detector control electronic module which is mounted on the right side of the GC. The
heater voltage enters the detector control module through the main jack on the
motherboard slot A, B, or C. The voltage is then passed through J9 to the ECD Heater.
Each detector control module slot has an independent heater channel on the Power
Control PCB. The temperature feedback from the detector RTD is also fed through
this module to the motherboard.
A jumper must be made on the motherboard to enable the RTD. Module A uses J8,
module B uses J7 and module C uses J6. The top two pins must be jumped to enable
the RTD.

Circuit Function
The main purpose of the Nitrogen Phosphorus Detector (NPD) PCB is to amplify the
low current produced from the detector and to supply its thermionic source.
A local single-chip microprocessor 68HC05 (U34), part of 74HC240 (U35A–B), and
four optocouplers 6N137 (I4–I7), control the SPI interface bus for the serial
communication (MOSI, SCK, CSI, MISO) to the main microprocessor (CPU PCB)
through the motherboard (J6, J7).
Integrated circuit MAX538 (U12) and amplifier TLO82 (U11A) generate the analog
output command VOLT (0–10 V) to select the polarization source circuit
(LM741, U21).
The input electrometer current amplifier circuit consists of:
•
Integrated circuits 5909 (U2), OP07 (U19), JFN FET (Q1–Q4), and OP07 (U20)
•
Resistors
•
Capacitors
•
Potentiometers
•
Diodes
The integrated circuit LM324 (U3A–U3C) gives the gain (1–3) commands to select
the range (0–3). The LM324 (U3D) gives the filter command to the input electrometer
through JFN FET (Q2).
Two digital/analog converters DAC0800 (U30–U31) and the amplifier OP07 (U25)
make up the zero suppression circuit (back-off current, 16 bits). The analog output of
the amplifier OP07 (U20) goes through TP15–TP16 (split points) to the integrated
circuit OP200 (U6A). The integrated circuit generates the analog output voltages of
0–1 V and 0–10 V for the integrator and computer external connections (J1, 4-pin).
The output of OP07 (U20) also goes to the OP07 amplifiers (U7, U8), a v/f converter
VFC110AP (U13), and an optocoupler 6N137 (I2) to generate a frequency output
(F-OUT, 0–4 MHz) to be read from the main microprocessor (CPU).
The regulator U4 (LM78L05) supplies the +5 VB. The regulator LM7815 (U36)
supplies the +15 VB. The regulator LM79L15 (U17) supplies the –15 VB.
Integrated circuit MAX538 (U5) is selected from the single-chip microprocessor
68HC05 (U34) signal (SEL_I) to enable the driving source current circuit. This circuit
consists of:

Adjustment Procedures
•
LM311 (U29)
•
NE555 (U32)
•
Transistors (Q7, Q8)
•
Resistors
•
Diodes
The amplifier OP07 (U26) and the amplifier TL082 (U28B) are a protection source
circuit for generating an alarm output signal (STS).
A special oscillator circuit is formed by:
•
Integrated circuit 4047 (U33)
•
Two transistors BC547 (Q16–Q17)
•
Resistors
•
Capacitors
•
A diode
This oscillator circuit is the primary supply of the internal transformer. The amplifier
LM741 (U21) is selected from the input VOLT (variable voltage 0–10 V) for
generating the source polarization voltage (0–100 V).
The regulator LM7815 (U23) supplies +15 V. The regulator LM7915 (U22) supplies
–15 V. The regulator 7805 (U24) supplies +5 V.
Two input voltages (8.5 V ac, 8.5 V ac 2) come from an external transformer in the
GC oven through the motherboard (J6). The P2 connector gives the 0 V (signal
common), 1 V, 10 V, and GND (chassis) outputs to connect an integrator or to handle
chromatograph data externally.
Output Specifications
+/–15 V @ 165 mA
100 V @ 0.01 A
+5 V @ 25 mA
Adjustment Procedures
No field adjustments are necessary.

The FPD pcb controls:
• input analogic current
• flame ignition
• photomultiplier voltage through the J5, J3, J4 and J1 connectors on the FPD
detector board.
The cell is independently heated and requires 100W @ 48 Vac (2 resistors 24V 50W
in series). Cell temperature is controlled by a FEEDBACK ANALOG pcb and CPU
pcb through the motherboard and PT100 temperature sensor.
On the J6 and J7 DIN64A connector, all voltages (24vdc, 8v, 5vdc, 0v, GND) and all
digital signals (F-OUT, CLK, Tx, Rx, CS, GF) interfacing with the motherboard bus
pcb are present. Two diodes, IN4148 (D28-D29), set the type of detector controller
automatically recognized by the main CPU microprocessor.
Service Manual
275
The electronic circuit created with 74HC240 (U22A/B), three 6N137 (I1,I3,I6)
and three 74HC595 (U9-U11) is a serial communication interface (SPI) between
the FPD pcb, the motherboard, and the CPU pcb bus connection.
IGNITER 48V A-B (from an additional transformer located in the Power Module)
and PT100 A-B signals are present on the J5 connector. The integrated circuit
2N5909 (U1), OP07 (U7), and OP07 (U14) with some resistors, and FET J201
(Q2) create the electrometer input current amplifier. The low input current signal
(pA) produced from the FPD is present at J2(N1).
The electronic circuit created by two LM358 (U26A/B) select the RANGE (10n;
0-1-2) through two bits, GAIN 1 and GAIN 0.
Two integrated circuits DAC0800 (U3-U4) and OP07 (U2) create the zero
suppression circuit by 16 bits input digital values (Z0-Z15).
The amplifier OP200 (U5A) takes the electrometer amplifier output (V_DET)
giving the analogic output voltages (0V, 1V, 10V, GND), which connect the
integrator or computer through terminal block J1 (SIGNAL_OUT).
Integrated circuits 4066 (U12D) and OP200 (U12B) hold the above analogic
outputs voltage when they are selected during the autozero.
Two amplifiers, 393 (U17A/B) and 6N137 (I5), give the output signal (GF) for a
gain of the frequency (1 bit, L=gain 1 or H=gain 32).
Two amplifiers OP07 (U6, U13), VFC110AP (U16) and 6N137(I4) have voltagefrequency-converter (0-10V to 0-3,5Mhz), which reads the CPU pcb through a
digital signal F-OUT.
The DC-DC converter 4047 (U21) takes the input voltage 24Vdc and using high
voltage resistors, transistors, diodes, transformer TR2, and the elevator voltage
circuit (D12-D19) generates a 800/900 v voltage. This is used for photomultiplier
excitation voltage.

Service Manual
285
Integrated circuits 2N5909 (U1), OP07 (U14), OP07 (U15) with some resistors,
and FET J201 (Q1-Q4) realize the electrometer input current amplifier. The low
input current signal (pA) produced from the PID detector is present to J2.
The electronic circuit is created by three 74HC00 (U7) and four LM324 (U2). The
RANGE (10n; 0-1-2-3) is selected by two bits, RNG L and RNG H.
Two integrated circuit DAC0800 (U4-U5) and OP07 (U3) create the autozero
circuit (Az) by 16 bits digital values.
The amplifier OP200 (U12A) takes the electrometer amplifier output (V_DET)
and passes it to the analogic output terminal (0V, 1V, 10V, GND), which connects
the integrator or computer.
Integrated circuits 4066 (U13D) and OP200 (U12B) hold the analogic outputs
voltage when they are selected during the autozero.
Two amplifiers 393 (U27A/B) and 6N137 (I9) select the output signal (GF) for a
frequency gain (1 bit, L=gain 1 or H=gain 32).
Two amplifiers OP07 (U6, U24), VFC110AP and 6N137 (I8) realize a
voltage-frequency-converter (0-10V to 0-3,5Mhz) read from the CPU pcb through
a digital signal F-OUT.
The electronic circuit has three transistors, TIP137 (Q10), BC237 (Q12), and
BU806 (Q9); resistors; capacitors; a transformer (TR1). Diodes (D23, D24, D27,
D32, D33) supplies -2000V to the PID detector lamp through the J7 connector.
The amplifier, LM358 (U23B), and optocoupler, CNY17 (I2), give the output
signal for the detector’s lamp status (LMP_ST; 0=OK, 1=OPEN CIRCUIT).
Two integrated circuits, 4066 (U16A/B) and optocoupler CNY17 (I1), are
selected from the input signal (LMP_H/L), and they activate two equal circuits,
which have two 4066 ( U16C/D) and two amplifiers (LM358 (U21A/B)) to get a
LOW or HIGH lamp current.

Theory of Operations
Circuit Functions
The HWDTRC pcb controls the TCD bridge filaments the 9 pole Male connector (P3).
The differential input amplifier INA114BP (U19) takes the unbalance input signal
from two points of the bridge detector through connector P3 (pin 6 and 2). Two
OP07C buffers (U25,U26) control two other bride detector points (sensing) through
connector P3 (pin 3 and 4).
Use RV1 potentiometer for COARSE ZERO adjustments. Use the AD7541AJP
(U20), with two OP07 amplifiers (U12, U13), is used for FINE ZERO adjustments.
Analogic output signals of the INA114BP (U19, pin 6) go to the input of two OP07
amplifiers (U11, Gain x 10 and U4, Gain x1), which are selected by digital-analogic
switch DG413 (U2, GSET).
A digital input signal (ENA0) selects the DG413 digital-analogic switch (U3) and the
OP07 amplifier (U1) to enable the analogic outputs (0V, 1V, 10V, GND), which are

present on the P2 terminal block. These outputs are used for external connections
to:
• A recorder
• An integrator
• A chromatography data handling system
The OP07 amplifier (U7) inverts the analogic signal polarity while the LP311N
comparator (U27) and 6N137 optocoupler (U31) give the "threshold" digital
output to the main microprocessor (P1). The analogic output of the OP07
(U14, pin 6) goes to the OP07 amplifier (U6, gain change) to be converted in
frequency by VFC110AP (U33). The output frequency (0-4Mhz at 0-10V) is then
optoisolated through 6N137 (U32) and read from the main microprocessor.
Integrated circuit PM7524 (U28) and amplifier OP07 (U29) generate two setpoints:
• Filaments Temperature (SETT), which is read through the comparator OP07
(U24) giving a CT (constant temperature) output signal.
• Filaments Voltage (SETV) which is read through the comparator OP07 (U23)
giving a CV (constant voltage) output signal.
Using the comparator OP07 (U10) to give a CC output signal, the amplifier OP07
(U16) reads the filaments current (10V max).
The purpose of the hybrid circuit CE 9760 (U15) is to memorize all internal
signals to be interfaced with the main microprocessor by a serial communication
(SPI). DC/DC converter IMR15 (U18) takes the +24 V input voltage to generate
two +/- 15 V (A-P) output voltages and regulator 7805 (Q3) generates a +5 V
voltage.
Regulator LT1021 (U30) and amplifier OP07 (U39) generate the -10 V voltage
(A). An additional 48V transformer and PT100 sensors are used for a second
TCD transfer line through connectors P7 (9 poles Female) and P1 (Bus mother
board).
Two IN4148 diodes (D19,D20) set the type of detector controller (for example
DETAB = TCD) for an automatic recognition by the motherboard’s main

microprocessor. The P2 connector gives the 1V/10V/OV/GND outputs to connect an
external integrator or data handling.
Output Specifications
+/-15 V @ 350 mA
+5 V @ 25mA
Adjustment Procedures
No field adjustments are necessary. The RV2, RV3, RV4, RV5 and RV7
potentiometers concerning the off-set and full-scale are factory adjusted.
Protection Circuits
The filament current is limited to 250 mA.
Special Notes
The CE9761(U40) hybrid circuit is present and the R54 resistance has a different
value only if the TCD detector bridge has two filaments instead of four.

Thermocouple Preamplifiers
Theory of Operations
Theory of Operations
Two inlet configurations require temperature feedback from thermocouples instead of
RTDs. These are the PTV and the OC HOT.
Refer to schematic 119834 in Schematics and Component Layout.
The thermocouple is an optional PCB which plugs onto the TFB & DIO PCB. It
amplifies and offsets the temperature signal, so the A/D on the TFB & DIO PCB can
input the temperature to the microprocessor.
The thermocouple amplifier is designed for use with a type E (Chromel/Constantan)
thermocouple.
Integrated circuit U2 provides a 2.5 V reference and a voltage proportional the
temperature of U2. Circuit U1(output pin 1) buffers the 2.5 V reference from U2 and
supplies it as a fixed offset to the summing amplifier U3.
Circuits U1(output pin 7) and U1(output pin 14) buffer and scale the temperature
output of U2 and supply it to the summing amplifier U3.
The thermocouple feeds the circuit via J2. Amplifier U1(output pin 8) buffers the
signal, which allows the thermocouple to be shorted to ground. The output of this
amplifier also feeds the summing amplifier U3.
The output of U3 is a voltage representing the temperature of the thermocouple. It has
been compensated for the unwanted thermocouple effects at J2.
Adjustment Procedures
No field are adjustments possible.

On-Column Semiautomatic Actuator
Theory of Operations
Theory of Operations
Some on-column inlet options include a semiautomatic actuator for opening and
closing the valve. These require a small PCB which must be installed on the
motherboard. If the system has two on-column actuators, then two of these PCBs can
be installed with one on top of the other.
The insertion of the syringe is sensed by an opto-interruptor (see schematic 119947 in
Schematics and Component Layout). A flag mechanism on the assembly causes the
beam to be unbroken when the syringe is inserted.
Inserting the syringe causes light from the LED to strike the phototransistor in the
opto-interruptor. This causes the signal SYR_IN to go high. As a result, the output of
U1 switches low. Transistor Q1 inverts the output of U1. These two signals are
buffered by U3, and control the valves which pneumatically open or close the valve in
the injector assembly.
A start pulse is generated by one-shot U2. Jumper E2 permits selection of the polarity
of the start pulse to be generated.
Adjustment Procedures
No field adjustments are necessary.
Schematics and Component Layout
The schematics and component layout information for the on-column semiautomatic
actuator PCB is listed below in Table 5.17-1. The number of drawings has been

PCB Replacement
PCB Replacement
The TRACE GC 2000 has a modular design intended for printed circuit board (PCB)
replacement. The complexity of the various PCBs used in the TRACE GC 2000
discourages component level troubleshooting. Troubleshooting to the PCB level may
require the use of specialized test equipment.
Digital Flowmeter
A variety of digital flowmeters are available for monitoring flows on the
TRACE GC 2000. Some flowmeters require selection of a specific gas type.
Monitoring detector flows on the TRACE GC 2000 may require the mixing of gas
types. To reduce errors in flow measurement, it is recommended you use a flowmeter
that is not gas type dependent. Hand-held digital flowmeters are available that are
independent of gas type. Digital bubble flowmeters intended for laboratory use are
also available.
Digital Voltmeter (DVM)
Troubleshooting and monitoring of voltages and resistance on the TRACE GC 2000
and its associated peripherals can be accomplished with a 3½ digit DVM. It is
recommended that the DVM have manual range selection as opposed to auto ranging.
The input impedance should be >10 meg ohm. Alligator-type clip leads (or similar)
should be available to make reliable contact to test points.
Oscilloscope
Most troubleshooting to isolate problems to the PCB level can be performed with a
DVM. Should an oscilloscope be required, it is recommended to use one with a
100 MHz time base, 5 mV to 50 V/division range, and an X1 and X10 selectable
input probe.
Leak Test Meter
The TRACE GC 2000 can perform an automatic injector leak test. However, it cannot
identify the actual location of the leak or identify leaks other than those associated
with the injector. Liquid leak detectors are not recommended since these may
introduce contaminates into the gas stream.
320
Service Manual
Leak Test Meter
Chapter 6.1
Recommended Test Equipment
Leak testing should be performed using an electronic leak detector. Portable as well
as bench-mounted electronic leak detectors are available for use. Most electronic leak
detectors calibrate using room air as a reference, so the detection of air leaks may not
be possible. Air supplied to a GC may have to be substituted with helium to perform
leak test of the air flow paths.

Range Parameter
The Range 10^ parameter is an input attenuation value. It is set from 0 (high

This means that if we have a small variation (in pA) of the baseline value when the
Range 10^ is set 0 or 1, the input amplifier circuit of FID card can read it, and,
according with threshold value set, can qualify the Flameout retry (if it is set ON).
If the Range 10^ is set 2 or 3, the small variation (in pA) of the baseline is not
detected from the FID card. For this reason, when the Range 10^ is set 2 or 3, the
Signal pA, Ign. thresh and Flameout retry parameters will be not displayed
in the DETECTOR FID menu.

Description
Standard
It supports the detectors FID, ECD, PID, FPD, TCD and the PTV Injector.
For NPD
It supports the NPD only.
It is already factory installed when the GC is equipped with a NPD.
- In the case the GC, equipped with a detector different than NPD, is upgraded
with a NPD, the transformer must be installed on the GC Power Control
Module.
- When the GC is upgraded with a second NPD, this transformer supports both.
NOTE
436
An obsoleted FID transformer is present in TRACE™ GC 2000 with FID having serial
number below than 983808 (Milan) or TR101089 (Austin).
