A significant uptake of supercritical mobile phases into immobilized stationary phases has been observed. The phase swelling effect has been evaluated hydrodynamically for SE-30, SE-54, and cyanopropyl silicone phases with respect to the mobilephase density of supercritical butane, column temperatur

Fused-silica capillary columns with internal diameters of 50 pm were coated with 0.25 to 1.0 pm films of SE-54 and evaluated under supercritical fluid chromatographic conditions using carbon dioxide as mobile phase. Experimental results compared well with theoretical predictions. There was no signif
