| Abstract: | Thin-layer adsorption chromatography with a multicomponent mobile phase is discussed. A new equation for predicting RM-values in TLC with mixed mobile phases using the RM-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 RM-data obtained by TLC using a binary mobile phase. |
