2.3.5.4 GC Module
The GC module is comprised of three parts: columns, chromatographic valve and
GC module circuit board. The valve controls the flow of gas within the system. The
columns perform the separation of the gas into component parts for analysis. The
GC module circuit board contains the sensors for the carrier pressure regulators,
the sample pressure sensor and the thermal conductivity detectors (TCDs) which
detect the different gas components as they leave the GC columns. It also
contains an EEPROM or FLASH memory for storage of calibration and
characterization information of the module and its sensors. Replacement is by
single bolt removal.
Figure 2-12 shows the GC module with the oven wall removed.
