INVESTIGATION OF HPLC PACKINGS BY LIQUID MIXTURE ADSORPTION

Abstract

The adsorption isotherms of methanol (1) - benzene (2) and benzene (1) - n-heptane (2) mixtures on four different HPLC silica gel were recorded to determine the types of the liquid mixture adsorption isotherms. Based on the experimental results, qualitative statements could be made regarding the relationship between chromatographic and mixture adsorption properties.
