Main scientific interests

(i) Modeling of solute retention in liquid chromatography (planar chromatography and HPLC) and derivation of the physically grounded mathematical relationships, coupling together quantitative composition of the employed multicomponent mobile phases with solutes' retention parameters;

(ii) Modeling of solute retention in gas chromatography and derivation of thermodynamic magnitudes (in the first instance, of the enthalpies of solutes' vaporization) from the gas chromatographic results as a handy alternative for the tedious non-chromatographic measurements; and

(iii) Modeling of intermolecular interactions (self-association and mixed association) among the analytes in planar chromatography (known as lateral interactions) and assessing the impact thereof on performance of the so-called 'difficult' separations.

Research co-operation

(i) In the years 1988 - 1996 with the late Prof. Emanuel Gil-Av, The Weizmann Institute of Science, Rehovot, Israel (modeling of enantiomer separation in gas liquid chromatography).

(ii) From the year 1996 onward, with Dr. Karoly Heberger, Institute of Chemistry, Chemical Research Center, Hungarian Academy of Sciences, Budapest, Hungary (modeling of solute retention in gas chromatography and - as a consequence -derivation of thermodynamic data from the gas chromatographic results).

(iii) From the year 1997 onward, with Prof. Krzysztof Kaczmarski, Faculty of Chemistry, Technical University of Rzeszow, Rzeszow, Poland (investigation and modeling of the intermolecular analyte - analyte interactions (i.e. lateral interactions) in planar chromatography and the impact thereof on the quality of separation).
