Part 4. Conditioning columns
Conditioning involves establishing a flow of carrier gas through a column and
then heating it for one-half hour for capillary columns and overnight for packed
columns. This drives off contaminants and makes the column fit for analytical
use.
New packed columns should be conditioned, since they often contain volatile
contaminants from the coating process. It may also be necessary to condition a
used column that has been stored for some time without end caps or plugs.
Conditioning is not as important with capillary columns since they contain a
minimal amount of stationary phase.
The following procedures include preliminary steps and the actual conditioning
procedure, which differs for packed and capillary columns.
