The GC Column and Oven
GC columns are located inside a temperature- controlled
oven. Generally, one end of the column is attached to the
inlet, while the other end is attached to the detector.
Columns vary in length, diameter, and internal coating. Each
column is designed for use with different compounds.
The purpose of the column and the oven is to separate the
injected sample into individual compounds as it travels
through the column. To aid this process, the GC oven can be
programmed to speed the sample flow through the column.
