Abstract

Several liquids have been tested under supercritical conditions for their suitability in chromatographic separations. Experimental pressures were up to about 150 atm, temperatures to 300°C; stationary phases of differing polarity were used. Stability under all experimental conditions is shown by cyclohexane, di-i-propylether, benzene, tetrahydrofuran and ethylacetate, while halogenated alkanes, branched alkanes, ketones and acetonitrile decompose in some cases.
