Abstract: | Summary In supercritical fluid chromatography (SFC), studies on binary eluents composed of pentane and diethyleneglycol dimethylether
were performed in the concentration rage of 5 to 15% of the ether compound and at pressures of 20 to 50 bar. Influences of
temperature, pressure and eluent composition on the behavior of the mobile phase were found to closely resemble those for
pentane-dioxane mixtures. Resolution depended on variations in capacity ratios, selectivities, and plate numbers. The critical
data for diethyleneglycol dimethylether were estimated by means of different group contribution methods. |
