Abstract

A unified approach to sequential gas and supercritical fluid Chromatography using 50 μm i.d. open tubular columns is described. Sample introduction is performed by means of a rotary injection valve. In order that linear velocities can be optimized independently, a second rotary valve in the chromatographic oven is used to direct the flow of column eluate to the flame ionization detector through either fused silica tubing in GC, or a frit restrictor in SFC.

Applications of sequential GC‐SFC on a 50 μm i.d. open tubular column are demonstrated, and comparisons made between sequential GC‐SFC on 50 and 100 μm i.d. columns.
