Injecting large volumes of solvent while the column is still installed is not rinsing a column nor does it remove any contaminants from the column. A capillary GC column must have a bonded and cross-linked stationary phase before it can be solvent rinsed. Solvent rinsing a non-bonded stationary phase results in severe damage to the column. Solvent is added to the vial, and the vial is pressurized using the gas source. The pressure forces solvent to flow through the column.
Residues dissolve into the solvent and are back flushed out of the column with the solvent.
The solvent is then purged from the column, and the column is properly conditioned. Insert the detector end of the column into the rinse kit. Multiple solvents are normally used tn rinse columns. Each successive solvent must be miscible with the previous one. High boiling point solvents should be avoided especially as the last solvent.
