5.7 GC Module
A GC module is a self-contained gas chromatograph that can perform sample
injection, separation, and detection. Up to two GC modules can be installed in a 2-
module chassis or up to four GC modules can be installed in a 4-module chassis,
each optimized to analyze different compounds from the same sample source.
5.7.1 Injection
A gas sample is injected into Micro GC Fusion through the front and is directed to one
or more GC modules simultaneously. The MEMS injector on the GC module contains
a sample loop and micro-diaphragm valves which are used to direct the sample and
carrier gas flows. The sample volume is determined by the Inject (ms) time setting in
the method. The injector temperature is also set in the method and can range from
30-100°C (86-212°F).
Micro GC Fusion supports four types of injectors:
• Variable Volume
• Variable Large Volume
• Fixed Volume
• Backflush, Fixed and Timed
