4.5 Theory of Operation
Gas chromatography is used to separate and analyze compounds in mixed gas
samples. A typical GC module consists of four main subsystems: injection, separation,
detection, and data system.
4.5.1 Injection
A sample is introduced into a GC system through its injector. Micro GC Fusion
accepts gas phase samples only at pressures ranging 0-172 kPa (0-25 psi).
Micro GC Fusion is equipped with a sample inlet system that distributes injected
sample to each injector on multiple GC modules within the instrument for
simultaneous analysis.
CAUTION
Micro GC Fusion is intended for gas sampling only. Liquid injections will
damage the instrument.
The optional Integrated Sample Conditioner is recommended when the sample gas is
at high pressure - up to 6,895 kPa (1,000 psi). The Integrated Sample Conditioner
reduces the sample gas pressure to approximately 83 kPa (12 psi) and heats the
sample to a constant temperature to optimize analysis repeatability.
Carrier gas, also known as the mobile phase, carries the injected sample into the
column for analysis. A high purity inert gas, free from hydrocarbons, oxygen and
moisture is required. Helium is preferred, while hydrogen, nitrogen, and argon are
viable options depending on application requirements.
Carrier gas with a purity of 99.999% is preferred. A purity of 99.995% is acceptable
when a carrier gas trap is installed.
