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

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

## Abstract A study has been undertaken on the effect of temperature on retention characteristics in thin‐layer chromatography (TLC) with low‐volatility mobile phases (MP). It is shown that temperature variations in TLC in melts bring about variations in both the relative retention values and, in s

A comparative study of chromatographic properties of different supercritical eluents has been performed by considering the retention at equal density or at equal free volume for different mobile phases. At equal density, t he temperature dependence of the capacity ratios of aromatic hydrocarbons is
