✦ Synopsis

Abstract

TLC experimental data have been measured for polycyclic hydrocarbons in binary and ternary mobile phases on silica gel. These data have been interpretated using the equation discussed by us in Part 1 of this series [HRC & CC 2 (1979) 236]. The heterogeneity parameter appearing in this equation has been evaluated and compared for different ternary and binary mobile phases.

## 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 heterogenei
