Acta Chrom. 6, 21-38 (1996). The possibility of using a thermodynamic approach for optimization of mixed mobile phases for systems with binary and ternary solvents is discussed, as well as the method for predicting separation results in column liquid chromatography on the basis of experimental thin-layer chromatographic data. The effect of mobile phase composition on solute retention is described by solute capacity factors (characteristic of the pure solvents), molecular interactions occurring in the bulk phase and adsorption equilibrium in a given adsorbent – binary solution system. Two kinds of chambers were used in the investigation: a saturated Stahl chamber and a sandwich chamber. The study described the use of different TLC techniques as pilot methods for HPLC.

J. Planar Chromatogr. 11, 350-352 (1998). Attempt to use a theoretical equation - so far applied to adsorption chromatography - in reversed-phase systems with two-component mobile phases. The four-parameter equation is based on an adsorption-partition mechanism for the chromatographic process. Agreement between theoretical and experimental retention was found to be good over the whole range of mobile phase concentrations investigated.
