Abstract:
In the Part 1 of this series a new equation for determining the Rm 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). The numerical values of m, evaluated for 13 chromatographic systems, have been compared with that of the O?cik's parameter A, which characterizes solute-solvent interactions.
