1Introduction
Chromatography Using a GC
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:
1Injecting a sample into the GC. (This takes place at the
inlet.)
2Separating the sample into individual components. (This
takes place inside the column in the oven.)
3Detecting what compounds were in the sample. (This is
done in the detector.)
During this process, status messages from the GC are
displayed, and user changes to parameter settings can be
made through the operating panel or data system.
Refer to the Advanced Operating Manual and the Getting
Started manual for more details.
