This section describes the contents and purpose of the Model 700 Gas
Chromatograph System Reference Manual, a description of the Model 700
system, an explanation of the theory of operation, and a glossary of
chromatograph terminology.
Use this section to get acquainted with the basic engineering of the
Model 700 product.
1.1 Description of manual
The Model 700 Gas Chromatograph System Reference Manual (P/N 39000-521) consists of installation, operations, and maintenance and
troubleshooting procedures. Also included is information about the
Software Name software interface.
1.2 System description
The Model 700 is a high-speed gas chromatograph (GC) system that is
engineered to meet specific field application requirements based on
typical natural gas stream composition and anticipated concentration of
the selected components. In its standard configuration, the Model 700
can handle up to four streams: typically, three for sample and one for
calibration.
The Model 700 system consists of three major parts: the analyzer
assembly, controller assembly, and sample conditioning system (SCS).
Model 700 subsystems are: a Flame Ionization Detector (Micro-FID), a
Liquid Sample Injector (LSIV) and a Methanator.

WARNING
3-9000-521 APRIL 2012
The GC-PC interface provides the user with the greatest capability, easeof-use, and flexibility. One PC running MON2000 can connect with up to
32 chromatographs (via RS-485 serial communications links). MON2000
is used to edit applications, monitor operations, calibrate streams, and
display analysis chromatograms and reports, which can then be stored
to files on the PC hard drive or printed from either the PC printer port or
the GC printer port.
1.2.3 Sample conditioning system (SCS)
The sample conditioning system is located between the process stream
and the Analyzer Assembly sample inlet (mounted on the lower portion
of the Analyzer Assembly stand). The standard configuration includes a
Stream Switching System and filters.
The Model 700 electronics and hardware are housed in two explosionproof enclosures and meet IEC Class I, Zone 1, Ex d IIB+H
1, Division 1, Groups B, C, and D) approval for use in a hazardous
environment.
, T4 (NEC Class

1.3 Functional description
A sample of the gas to be analyzed is taken from the process stream by a
sample probe installed in the process line. The sample passes through a
sample line to the SCS where it is filtered or otherwise conditioned. After
conditioning, the sample flows to the Analyzer Assembly for separation
and detection of the gas components.
Do not use a PC or a printer in a hazardous area. Serial port and Modbus
communications links are provided to connect the unit to the PC and to connect to
other computers and printers in a safe area. Failure to follow this warning may result in
injury or death to personnel or cause damage to the equipment.
The chromatographic separation of the sample gas into its components
is accomplished in the following manner. A precise volume of sample gas
is injected into one of the analytical columns. The column contains a
stationary phase (packing) that is either an active solid or an inert solid
1 - 8
Model 700 Gas Chromatograph System Reference Manual
APRIL 2012 3-9000-521
support that is coated with a liquid phase (absorption partitioning). The
sample gas is moved through the column by means of a mobile phase
(carrier gas). The selective retardation of the components takes place in
the column, causing each component to move through the column at a
different rate. This separates the sample into its constituent gases and
vapors.
A detector located at the outlet of the analytical column senses the
elution of components from the column and produces electrical outputs
proportional to the concentration of each component. Outputs from the
detector(s) are amplified in the Analyzer Assembly electronics, then
transmitted to the Controller Assembly for further processing.
Note
For additional information, see "Section 1.5: Theory of operation".
Output from the Controller Assembly is normally displayed on a
remotely located PC or a printer. Connection between the Controller
Assembly and the PC can be accomplished via a direct serial line or via a
Modbus-compatible communication interface.
Several chromatograms may be displayed via MON2000, with separate
color schemes, allowing the user to compare present and past data.
Use of the MON2000 software for configuration and troubleshooting
procedures is essential in most cases. The PC may be remotely
connected via telephone, radio or satellite communications. Once
installed and configured, the Model 700 can operate independently for
long periods of time.

1.4 Software description
The MON2000 uses three distinct types of software. This enables total
flexibility in defining the calculation sequence, printed report content,
format, type and amount of data for viewing, control and/or
transmission to another computer or Controller Assembly. The three
types are:
• Baseline Operating System (BOS)
• Application configuration software
• Maintenance and Operations software (MON2000 version 2.2 or
later)
The BOS and the Application configuration software are installed when
the Model 700 system is shipped. The application configuration is
tailored to the customer’s process and shipped on a floppy disk. Note
that the hardware and software are tested together as a unit before the
equipment leaves the factory. MON2000 communicates with the Model
700 system and allows an initial site system setup (i.e., operational
parameters, application modifications, and maintenance).

System Reference Manual Model 700 Gas Chromatograph
3-9000-521 APRIL 2012
1.4.1 BOS
The Baseline Operating System (BOS) supervises operation of the Model
700 through its internal microprocessor-based controller; all direct
hardware interface is via this control software. It consists of a multitasking program that controls separate tasks in system operation, as well
as hardware self-testing, user application downloading, start-up, and
communications. Once configured, a Model 700 can operate as a stand
alone unit.
1.4.2 MON2000
MON2000, available as a Windows-based program, provides the humanmachine interface for maintenance, operation, and troubleshooting. It
allows the user to download applications developed for a specific GC
unit. MON2000 provides operator control of the connected Model 700,
monitors analysis results, and inspects and edits various parameters that
affect Model 700 operation. It also controls display and printout of the
chromatograms and reports, and it stops and starts automatic analysis
cycling or calibration runs.
After the equipment/software has been installed and the operation
stabilized, automatic operation can be initiated. The link between the
MON2000 computer and the Model 700 can either be direct, via a local
serial connection or remote, via an ethernet network, modems,
telephone lines and/or radio.
Operation of multiple Model 700 chromatographs (up to 32) with a
single MON2000 computer, via a multi-drop serial link, is also supported.

1.5 Theory of operation
The following sections discuss the theory of operation for the Model
700, the engineering principles and concepts used.
Note
See "Section 1.8: Glossary" for definitions of the terminology used in the following
explanations.
1.5.1 Thermal conductivity detector (TCD)
One of the detectors (located on the oven in the Analyzer upper
assembly) is a thermal conductivity detector that consists of a balanced
bridge network with heat sensitive thermistors in each leg of the bridge.
Each thermistor is enclosed in a separate chamber of the detector block.
One thermistor is designated the reference element and the other the
measurement element. See Figure 1-5 for a schematic diagram of the
thermal conductivity detector (TCD).
1 - 13
System Reference Manual Model 700 Gas Chromatograph
3-9000-521 APRIL 2012
Figure 1-5. Analyzer assembly with tcd detector bridge
In the quiescent condition (prior to injecting a sample), both legs of the
bridge are exposed to pure carrier gas. In this condition, the bridge is
balanced and the bridge output is electrically nulled. (The bridge can be
balanced by the fine and coarse adjustment potentiometers located on
the preamplifier circuit board.)
The analysis begins when a fixed volume of sample is injected into the
column by operation of the sample valve. The sample is moved through
the column by the continuous flow of carrier gas. As successive
components elute from the column, the temperature of the
measurement element changes.
The temperature change unbalances the bridge and produces an
electrical output proportional to the component concentration.
The differential signal developed between the two thermistors is
amplified by the preamplifier. Figure illustrates the change in detector
electrical output during elution of a component.

In addition to amplifying the differential signal developed between the
two thermistors, the preamplifier supplies drive current to the detector
bridge. The voltage signal is converted to a 4-20 milliampere (mA)
current loop for transmission to the Controller Assembly.
The signal is proportional to the concentration of a component detected
in the gas sample. The preamplifier provides four different gain channels
as well as compensation for baseline drift.
The signals from the preamplifier are sent to the Controller Assembly for
computation, recording on a printer, or viewing on a PC monitor (via
MON2000).

1.5.2 Flame ionization detector (FID)
The other detector (located on the oven in the Analyzer Assembly) is a
Flame Ionization Detector. The FID requires a polarization voltage and its
output is connected to the input to a high impedance amplifier which is
called an Electrometer. The burner uses a mixture of hydrogen and air to
maintain the flame. The sample of gas to be measured is also injected
into the burner. See Figure 1-7 for a schematic diagram of the Flame
Ionization Detector (FID).

1.5.3 LSIV
The Liquid Sample Inject Valve (LSIV) penetrates the wall of the upper
enclosure and is held in place by a retaining ring. The mounting
arrangement is designed to ensure integrity of the flameproof enclosure.
Figure 1-8. Model 700 LSIV assembly
The outermost end houses an air operated piston. Air at 15 to 45 psi is
directed by a solenoid valve to either advance the stem to inject the
sample or to retract the stem.
The next section houses an auxiliary stem seal assist. A piston driven by
air at 80 to 100 psi keeps adequate load on the stem seal to counteract
wear at the high temperatures and pressures that might be encountered.
There are two ¼npt ports in this section; one port retracts the sample
piston and the other port activates the seal assist.
The innermost section houses the stem seals and the sample chamber.
There are five ¼ npt ports in this section.

3-9000-521 APRIL 2012
Within the enclosure cavity are the flash chamber components
surrounded with insulating covers. At working temperatures, the
surfaces of these covers become very hot to the touch.
The tip of the LSIV is the port where flashed sample is taken to the oven
system.
The port at right angles to the length of the LSIV is the input for carrier
gas.
The heater block, a cylinder of aluminum, is installed off-center
surrounding the flash chamber, close to the wall of the upper enclosure.
It houses the heater and an RTD and is retained by a jamb nut that should
only be finger tight.
1.5.4 Methanator
After all other components have been separated from the sample,
normally undetectable CO and CO2 are sent through the methanator.
They are combined with hydrogen to make methane in a heat generated
catalytic reaction. The methanator is also known as a methanizer or a
catalytic converter.

1.5.5 Data acquisition
Every second, exactly 40 equi-spaced data samples are taken (i.e., one
data sample every 25 milliseconds) for analysis by the Controller
Assembly. The sampling frequency of 40 Hertz (Hz) was chosen to
reduce normal mode noise (at 60 Hz).
After each point on the chromatograph signal is sampled, the resulting
number is stored for processing in a buffer area of the Controller
Assembly memory. During the analysis, only the last 256 data points are
available for processing.
Because the data analysis is done as the signal is sampled (in real-time),
only a limited number of past data samples is required to analyze any
signal.
1 - 19
System Reference Manual Model 700 Gas Chromatograph
NPW=
3-9000-521 APRIL 2012
As a part of the data acquisition process, groups of incoming data
samples are averaged together before the result is stored for processing.
Non-overlapping groups of N samples are averaged and stored, and thus
reduce the effective incoming data rate to 40/N samples per second. For
example, if N = 5, then a total of 40/5 or 8 (averaged) data samples are
stored every second.
The value for the variable N is determined by the selection of a Peak
Width parameter (PW). The relationship is
where PW is given in seconds. Allowable values of N are 1 to 63; this
range corresponds to PW values of 2 to 63 seconds.
The variable N is known as the integration factor. This term is used
because N determines how many points are averaged, or integrated, to
form a single value. The integration of data upon input, before storing,
serves two purposes:
• The statistical noise on the input signal is reduced by the square root
of N. In the case of N = 4, a noise reduction of two would be realized.
• The integration factor controls the bandwidth of the chromatograph
signal. It is necessary to match the bandwidth of the input signal to
that of the analysis algorithms in the Controller Assembly. This
prevents small, short-duration perturbations from being recognized
as true peaks by the program. It is therefore important to choose a
Peak Width that corresponds to the narrowest peak in the group
under consideration.
1.5.6 Peak detection
For normal area or peak height concentration evaluation, the
determination of a peak's start point and end point is automatic. The
manual determination of start and end points is used only for area
calculations in the Forced Integration mode. Automatic determination of
peak onset or start is initiated whenever Integrate Inhibit is turned off.
Analysis is started in a region of signal quiescence and stability, such that
the signal level and activity can be considered as baseline values.
1 - 20
Model 700 Gas Chromatograph System Reference Manual
APRIL 2012 3-9000-521
Note
The Controller Assemblysoftware assumes that aregion of signal quiescenceand
stability will exist.
Having initiated a peak search by turning Integrate Inhibit off, the
Controller Assembly performs a point by point examination of the signal
slope. This is achieved by using a digital slope detection filter, a
combination low pass filter and differentiator. The output is continually
compared to a user-defined system constant called Slope Sensitivity. A
default value of 8 is assumed if no entry is made. Lower values make peak
onset detection more sensitive, and higher values make detection less
sensitive. Higher values (20 to 100) would be appropriate for noisy
signals, e.g. high amplifier gain.
Onset is defined where the detector output exceeds the baseline
constant, but peak termination is defined where the detector output is
less than the same constant.
Sequences of fused peaks are also automatically handled. This is done by
testing each termination point to see if the region immediately following
it satisfies the criteria of a baseline. A baseline region must have a slope
detector value less than the magnitude of the baseline constant for a
number of sequential points. When a baseline region is found, this
terminates a sequence of peaks.
A zero reference line for peak height and area determination is
established by extending a line from the point of the onset of the peak
sequence to the point of the termination. The values of these two points
are found by averaging the four integrated points just prior to the onset
point and just after the termination points, respectively.
The zero reference line will, in general, be non-horizontal, and thus
compensates for any linear drift in the system from the time the peak
sequence starts until it ends.
In a single peak situation, peak area is the area of the component peak
between the curve and the zero reference line. The peak height is the
distance from the zero reference line to the maximum point on the
component curve. The value and location of the maximum point is
1 - 21
System Reference Manual Model 700 Gas Chromatograph
3-9000-521 APRIL 2012
determined from quadratic interpolation through the three highest
points at the peak of the discrete valued curve stored in the Controller
Assembly.
For fused peak sequences, this interpolation technique is used both for
peaks, as well as, valleys (minimum points). In the latter case, lines are
dropped from the interpolated valley points to the zero reference line to
partition the fused peak areas into individual peaks.
The use of quadratic interpolation improves both area and height
calculation accuracy and eliminates the effects of variations in the
integration factor on these calculations.
For calibration, the Controller Assembly may average several analyses of
the calibration stream.
1.6 Basic analysis computations
Two basic analysis algorithms are included in the Controller Assembly:
Note
For additional information about other calculations performed, see the MON2000
Software for Gas Chromatographs User Manual (P/N 3-9000-522).
• Area Analysis — calculates area under component peak
• Peak Height Analysis — measures height of component peak
1.6.1 Concentration analysis - response factor
Concentration calculations require a unique response factor for each
component in an analysis. These response factors may be manually
entered by an operator or determined automatically by the system
through calibration procedures (with a calibration gas mixture that has
known concentrations).
The response factor calculation, using the external standard, is:

Auto Zero
Automatic zeroing of the TCD preamplifier may be configured to take
place at any time during the analysis when either the component is not
eluting or the baseline is steady.
The FID is automatically zeroed at each new analysis run and can be
configured to take place anytime during the analysis when either the
component is not eluting or the baseline is steady. The TCD is only
automatically zeroed at the start of a new analysis.

Baseline
Signal output when there is only carrier gas going across the detectors.
In a chromatogram you should only see Baseline when running an
analysis without injecting a sample.
Carrier Gas
The gas used to push the sample through the system during an analysis.
In C6+ analysis we use Ultra Pure (zero grade) Carrier Gas for the carrier.
This gas is 99.995 percent pure.
Chromatogram
A permanent record of the detector output. A chromatograph is
obtained from a PC interfaced with the detector output through the
Controller Assembly. A typical chromatogram displays all component
peaks, and gain changes. It may be viewed in color as it is processed on a
PC VGA display. Tick marks recorded on the chromatogram by the
Controller Assembly indicate where timed events take place.
Component
Any one of several different gases that may appear in a sample mixture
For example, natural gas usually contains the following components:
nitrogen, carbon dioxide, methane, ethane, propane, isobutane, normal
butane, isopentane, normal pentane, and hexanes plus.
Condulet
A box with a removable cover providing access to wiring in conduit

3.1.4 Signal wiring
Follow these general precautions for field wiring digital and analog
input/output (I/O) lines:
Observe all precautionary signs posted on the Model 700 enclosure. Applicable to all
digital and analog I/O lines connecting to the GC: Any loop of extra cable left for service
purposes inside the GC housing must not be placed near any AC power lines. If this
precaution is not followed, the data and control signals to and from the GC can be
adversely affected.
• Metal conduit must be used for all process signal wiring (assuming
operation in a Class 1, Division 1 Explosive Area). Metal conduit is not
required for use in general purpose areas.
• Metal conduit or cable (in compliance with EN 60079-14) used for
process signal wiring must be grounded at conduit support points
(intermittent grounding of conduit helps prevent induction of
magnetic loops between the conduit and cable shielding).
• All process signal wiring should be a single, continuous length
between field devices and the GC. If, however, length or conduit runs
require that multiple wiring pulls be made, the individual conductors
must be interconnected with suitable terminal blocks.
• Use suitable lubrication for wire pulls in conduit to prevent wire
stress.
• Use separate conduits for AC voltage and DC voltage circuits.
• Do not place digital or analog I/O lines in same conduit as AC power
circuits.
• Use only shielded cable for digital I/O line connections.
- Ground the shield at only one end.
- Shield-drain wires must not be more than two AWG sizes smaller
than the conductors for the cable.
• When inductive loads (relay coils) are driven by digital output lines,
the inductive transients must be diode-clamped directly at the coil.
• Any auxiliary equipment wired to the GC must have its signal
common isolated from earth/chassis ground.

Model 700 Gas Chromatograph System Reference Manual
APRIL 2012 3-9000-521
3.1.5 Electrical and signal ground
Follow these general precautions for grounding electrical and signal
lines:
• For shielded signal conducting cables, shield-drain wires must not be
more than two AWG sizes smaller than the conductors for the cable.
Shielding is grounded at only one end.
• Metal conduit used for process signal wiring must be grounded at
conduit support points (intermittent grounding of conduit helps
prevent induction of magnetic loops between the conduit and cable
shielding).
• A single-point ground (the outside case ground lug) must be
connected to a copper-clad, 10-foot long, 3/4-inch diameter steel
rod, which is buried, full-length, vertically into the soil as close to the

• All interior enclosure equipment-grounding conductors must be
protected by metal conduit.
• External equipment, such as data printers, that are connected to the
GC should be powered via isolation transformers to minimize the
ground loops caused by the internally shared safety and chassis
grounds.
3.1.6 Electrical conduit
Follow these general precautions for conduit installation:
• Conduit cutoffs must be square. Cutoffs must be made by a cold
cutting tool, hacksaw, or by some other approved means that does
not deform the conduit ends or leave sharp edges.
• All conduit fitting-threads, including factory-cut threads, must be
coated with a metal-bearing conducting grease, such as CrouseHinds STL or equivalent, prior to assembly.
• Temporarily cap the ends of all conduit runs immediately after
installation to prevent accumulation of water, dirt, or other
contaminants. If necessary, swab out conduits prior to installing the
conductors.
• Install drain fittings at the lowest point in the conduit run; install seals
at the point of entry to the GC explosion-proof housing to prevent
vapor passage and accumulation of moisture.
• Use liquid-tight conduit fittings, such as Myers Scru-tite or similar, for
conduits exposed to moisture.
When conduit is installed in hazardous areas (e.g., areas classified as NEC
Class I, Division 1, Groups B, C, and D), follow these general precautions
for conduit installation:
3 - 13
System Reference Manual Model 700 Gas Chromatograph
WARNING
3-9000-521 APRIL 2012
Observe all precautionary signs posted on the equipment. Consult your company
policies and procedures and other applicable requirements documents to determine
wiring and installation practices that are appropriate for hazardous areas. Failure to do
so may result in injury or death to personnel or cause damage to the equipment.
• All conduit runs must have a fitting, which contains explosion-proof
sealing (potting) located within 18 inches from the conduit entrance
to the explosion-proof housing.
• The conduit installation must be vapor tight, with threaded hub
fittings, sealed conduit joints and gaskets on covers, or other
approved vapor-tight conduit fittings.
3.1.7 Sample system requirements
Observe the following guidelines for installing GC sample systems:
Line length:
If possible, avoid long sample lines. In case of a long sample line, flow
velocity can be increased by decreasing downstream pressure and using
by-pass flow via a speed loop.
Note
Stream switching requires a sample pressure of 20 psig.
Sample line tubing material:
Note
The calibration gas stream inlet is the last stream inlet following the sample gas.
• Use stainless steel tubing for noncorrosive streams.
• Ensure tubing is clean and free of grease (see Figure 3-7 for details).
