A form of column chromatography where the mobile phase is a gas whereas the stationary phase is a liquid, e.g. a liquid silicone material as small beads packed in a long column


Supplement

This technique is usually applied in industrial settings and research in chemistry. It is not a common technique in biochemical processes because high molecular weight biomolecules, such as amino acids are easily denatured from heat during the process.
