3000 Micro GC Operating Manual
3.3 The 3000 Micro GC Module
3000 Micro GC utilizes a modular GC platform, which can simultaneously analyze
samples from one to four independent 3000 Micro GC channels. Each channel (or
module) is a self-contained GC that performs sample injection, separation, and
detection on a set of target components.
When installed in a 3000 Micro GC chassis, a module is referred to as a channel.
When standalone, it is referred to as a module.
Modules may be referred to as Channel A, B, C, D or 1, 2, 3, 4 from left to right.

3.3.1 Principle of 3000 Micro GC Module Operation
The major functions of the 3000 Micro GC module operation are: injection,
separation, and detection.
1 Injection: Gaseous sample is injected into 3000 Micro GC through the heated
inlet manifold. The manifold regulates the sample temperature and directs it
into the 3000 Micro GC injector flow assembly on a module. The sample is
drawn by vacuum pump through the injector sample loop and is released onto
the column.
