## Abstract A versatile and simple system is described that allows variation of the column flow rate in open‐tubular capillary supercritical fluid chromatography using both on‐column and postcolumn detection. The system is based on column‐effluent splitting in a low‐dead‐volume T piece at the colum

The theoretical and practical implications of simultaneous temperature/pressure and synchronized density/temperature programming are considered. Examples are shown for separations of dimethylpolysiloxanes where these techniques provide superior separation over their analogous isothermal programming
