GC Parts Description
36 Instruction Manual
Carrier Gas Inlet Port
It is located on the middle upper part of the instrument rear panel. Gas inlet port
are directly connected to the detector modules.
WARNING! Gas pressure must be controlled on the gauges provided on the gas tank of the
supply gas line. The maximum inlet pressure at 1000 kPa (145 psi) should be set to
allow DPFC module to adjust pressure up to 1000 kPa.
Commonly used gas are helium, hydrogen and nitrogen.
The default pressure unit is the kilopascal (kPa). You specify the pressure units in
the
Configuration
menu.
The following gives a brief conversion guide for the most commonly used
pressure units.
100 kPa = 1 bar = 14.51 psi
Detector Gases Inlet Ports
They are located on the middle upper part of the instrument rear panel. Detector
gas inlet ports are directly connected to the DGFC module.
WARNING! Pressure of the supply gas lines should be set to a minimum of 400 kPa (60 psi) to
ensure the regulation of detector gases.
Maximum input pressure to FOCUS GC (from supply gas lines) is 1000 kPa (145 psi).
Servo Air for Gas Sampling Valve Inlet Port
It is located on the left upper part of the instrument rear panel. Servo air inlet port
is directly connected to the gas sampling valve when installed into the GC.
