analyzer chassis. They are accessible by opening the front door of the
analyzer.
Adjustments are made using the appropriate control on the front
panel.
The analyzer contains three separate isothermal chambers
‘SAMPLE’, ‘FID’, and ‘COLUMN’ that are controlled by individual
PID temperature controllers. These controllers with integral readout
display are visible just behind the front panel as shown in Figure 2-1.

The sample chamber contains the 10-port GC switching valve and 2
sample loops. The ‘FID’ chamber contains the flame, pressure
regulators, pressure gauges and flow restrictors used by the FID
detector. The ‘COLUMN’ is housed in a separate ‘COLUMN’ enclosure
and maintained at a temperature of 70° C by its PID temperature
controller. The actual temperature setpoint for your instrument may be
different depending on the application. It is listed in the Addendum and
Testing Results section of Appendix B.
2.3.2 Gas Flow Control System
The analyzer is equipped with ports for the introduction of air, fuel,
carrier gas, span, and sample gas. It is imperative that these gases are
