Introduction

Chromatography Using a GC

10
Chromatography is the separation of a mixture of
compounds into individual components.
There are three major steps involved with separating and
identifying components of a mixture using a GC. They are:
1 Injecting a sample into the GC. (This takes place at the
inlet.)
Separating the sample into individual components. (This
2
takes place inside the column in the oven.)
3 Detecting what compounds were in the sample. (This is
done in the detector.)
During this process, status messages from the Agilent 7820A
GC are displayed, and user changes to parameter settings
can be made through the software keypad.
