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.)
2 Separating the sample into individual components. (This
takes place inside the column in the oven.)
3 Detecting what compounds were in the sample. (This is
done in the detector.)
