Comparison of Adsorption in Liquid-Solid Chromatography on the Basis of Different Models of Retention

Two models of retention in liquid adsorption chromatography have been evaluated. Terms related to adsorption from two equations based on different retention models were compared. The terms were calculated for selected substances in four chromatographic systems with a different polar modifier. Analysis of the data has proved the comparability of the terms and that they can be used interchangeably to describe adsorption phenomena. A regular relationship was found between the terms.
