EQUIPMENT DESCRIPTION

The Process Gas Chromatograph PGC2000 separates and measures the individual components of
gas or liquid samples. It automatically samples and analyzes process streams, using the analyzer's
Gas Chromatograph Controller (GCC) to control analytical functions. The analyzer (see Figure 1-1)
may be mounted on a wall, a rack, or a floor stand. It includes an insulated, air-heated Oven
Compartment, a Gas Chromatograph Controller, a purge air panel, and a pressure control panel.
Figure 1-1. TYPICAL PROCESS GAS CHROMATOGRAPH PGC2000
The Oven Compartment houses an isothermal oven which contains the analytical columns, the
detectors, and the sample valves.
The Gas Chromatograph Controller (GCC) contains the card cage with PCBs, the Temperature
Controller, and one or more of the following detector amplifiers: flame ionization (FID), thermal
conductivity (TCD), and flame photometric (FPD). The front panel has a liquid crystal display (LCD),
keyboard, and controller board. The FPD assembly itself is located in a special cabinet mounted on
the left side of the analyzer.
Below the GCC are the Purge Air Panel and the Pressure Control Panel. The Purge Air Panel
contains the heater air and purge air gauges and regulators. The Pressure Control Panel contains
the Electronic Pressure Controller (EPC) or a group of mechanical regulators and gauges. When the
EPC is installed the Pressure Control Panel has a blank front panel.
