✦ Synopsis

Abstract

Thin‐layer adsorption chromatography with a multicomponent mobile phase is discussed. A new equation for predicting R~M~‐values in TLC with mixed mobile phases using the R~M~‐ValUeS obtained for pure solvents is proposed. This equation takes into account effects of energetic heterogeneity of the adsorbent surface with regard to adsorbed molecules of solvents and solutes. Experimental verification of this equation is presented for R~M~‐data obtained by TLC using a binary mobile phase.

## Abstract In the Part 1 of this series a new equation for determining the R~m~ values in TLC with mixed mobile phases was proposed and examined by using the parameter m, which is a measure of energetic heterogeneity of the adsorbent surface with regard to the adsorbing molecules (admolecules). T
