Chromatographia 42, 675-679 (1996). Verification of the hypothesis that in salting-out planar chromatography there is a linear dependence between the pair of RM values of substances obtained on one or two sorbents using the same series of aqueous ammonium sulfate solution-RM proportionality between the distance of the individual points on the regression straight line and the difference in mol% of the salt in the corresponding solvent - proportionality rule.

J. Chromatogr. 350, 151-168 (1985). TLC on silica with four developing systems: 1) ethyl acetate - methanol - 30% NH3 85:10:5, 2) cyclohexane. - toluene - diethylamine 65:25:10, 3) ethyl acetate - chloroform 5:5, 4) acetone with the plate dipped in KOH solution. Detection by spraying with Dragendorff reagent and acidified iodoplatinate solution. A two-component model accounting for 73% of the total variance. Results of great practical importance in analytical toxicology.

J. Chromatogr. 365, 63-72 (1986). Description of the separation of polar compounds based on the upper section of the "prisma" model for mobile phase optimization. Separation of ginsenosides as an example of application of the model without modifier and of the separation of flavonoid glycosides with a modifier.

J. Planar Chromatogr. 1, 231-234 (1988). TLC on silica and RP-silica having varied pH values with n-hexane, ether, ethyl acetate, toluene, chloroform, THF, benzene, acetone, dioxane, methanol, acetonitrile, methyl butyl ketone for TLC and distilled water for reversed-phase TLC. Detection under UV 366 nm. Discussion of the effect of surface pH value of silica on the retention of dansyl amino acids and the differences between TLC and reversed-phase TLC.

Fres. J. Anal. Chem. 336, 419-422 (1990). TLC of all lanthanoids except Pm in aqueous solutions of five alkali metal chlorides on silica. Visualization by spraying with 0.02% aqueous arsenazo(III) solution and 1 mol/L acetic acid. Examination of the effects of the solvent cations and the solvent anions on the Rf values. Discussion of effects of the salt concentrations on Rf values. For the separation of groups of adjacent lanthanoids typical chromatograms are presented.

J. Chromatogr. 550, 667-675 (1991). Comparison of the log k’ values of 21 natural and synthetic deoxyuridine derivatives from HPLC with the RM values from TLC on alumina with water - 2-propanol 1:9 and 85:15, or dichloroethane - methanol - acetic acid 50:50:0.01. Discussion of the correlation between log k’ and RM values, and the influence of the length of the alkyl chain, of the substituent at position 5 of deoxyuridine on the retention. Influence of the presence of double and triple bounds in the substituent on the retention in different systems.

J. Planar Chromatogr. 12, 51-57 (1999). Analysis of the modern terminology of planar chromatography and suggestion of new variants. Some possible new directions in over-pressured TLC are considered.
