Comparison of retention behaviour of different supports - determination of lipophilicity of amino acids by RP TLC using silica gel, alumina, cellulose, Kieselguhr and their mixtures.

J. Liquid Chromatogr. 9, 1837-1847 (1986). Presentation of general dependence of the capacity ratio on the composition of the multicomponent mobile phase and consideration of the effects connected with difference of molecular sizes of solutes and solvents. A simple linear dependence for the binary mobile phase is proposed and tested on experimental data

Chromatographia 25, 324-326 (1988). TLC on silica with one-, two- and three component solvent systems. Study of the linear dependence of the chelate ring contraction on their Rf values in one-component solvent systems; in octahedral and square planar cationic complexes containing two identical five-membered chelate rings formed by three different ketoanils.

J. Chromatogr. Sci. 27, 540-544 (1989). Reversed-phase TLC of 22 peptides on paraffin-impregnates silica with methanol, ethanol or propanol. Study of the dependence of the silanophyl effect on the chemical structure of peptides and on the type of organic mobile phase.

J. Planar Chromatogr. 4, 328-329 (1991). TLC of dihydroxyanthraquinones (1,2-, 1,4-, 1,5-, 1,8, 2,6-) on Kieselguhr G impregnated with paraffin oil and binary mixtures of methanol and water 10:0, 9:1, 8:2, 7:3 and on cellulose with methanol - water 9:1. Detection under UV 254 nm (on Kieselguhr) and by spraying with 0.005% aqueous new fuchsin solution (on cellulose).

J. Liquid Chromatogr. 16, 1833-1843 (1993). Normal-phase, reverse-phase and chelation TLC of Pb2+, Hg22+, Hg2+, Ti+, Bi3+, Sn4+, and Sb3+ on silica, silica impregnated with DMSO or 20% tributyl amine or 20% tributyl phosphate in benzene, and silica impregnated with EDTA, with DMSO - HNO3 and DMSO - HCl systems as mobile phases. Discussion of the effect of solvent composition on migration of cations, and the effect of EDTA and DMSO on Rf values. Quantitative separation of Pb2+ from the others.

Acta Chromatographica 3, 70-83 (1994). Description of a simple but reliable method for the determination of coverage density, based on the semiempirical retention model authored by Kowalska, which enables rapid determination. The accuracy of the method was checked against a selection of experimental results.

Visualization with an aqueous solution of new fuchsine. Separation of 6-, 7-, and 8-methylquinoline, of alkoxyphenols, and of polycyclic aromatic hydrocarbons under similar conditions. Separation of the investigated isomers by RPTLC and attempt of at least qualitative correlation between the numerical values of RM with the numerical values of topological indices for evaluation of the hydrophobicity of the investigated isomers.
