Introduction
The 6850 Gas Chromatograph (GC) is a single-channel instrument with one
inlet, a column oven, a detector, a simple keypad, and a display as shown in
Figure 1.
To use it, you create a set of operating instructions, called a method, using the
optional G2629A Control Module or a computer-based control device such as
Agilent ChemStation or Agilent Cerity Networked Data System for Chemical
QA/QC (Cerity Chemical). You can load and store these methods on your GC.
You can also:
• Use a sample introduction system, such as an automatic injector or gas or
liquid sampling valve, to automate analyses.
• Use the Control Module to transfer methods from one 6850 GC to another,
store methods on a PC flash memory card, diagnose problems in your
instrument, and perform tests and checks.
