Determination of parameters characterizing TLC systems. J.Liquid Chromatogr. 6, 81-93 (1983). Discussion of an equation, derived in terms of the thermodynamic formulation of TLC with mixed mobile phase. The parameters of this equation, describing solute-solvent interactions in thermolabile phase and phase-exchange equilibrium between molecules of both solvents are determined by using its linear forms. These linear relationships have been examined by applying the TLC data for eight different binary mobile phases.

J. Xiangtan Univ. 1, 77-80 (1987) (Xiangtan Daxue Ziran Kexue Xuebao). TLC on primary amine N1923-silica with sulfuric acid. The plot of log (1/Rf-1) against the atom numbers of the rare earths divides the rare earths into 4 groups following the order of atom number: La-Nd, Pm-Gd, Gd-Ho and Ho-Lu.

Part V. J. Planar Chromatogr. 7, 41-49 (1994). TLC of aromatic alcohols on silica with carbon tetrachloride - ether - ethyl acetate 8:2:1, detection with a basic solution of thymol blue. Investigation of the correlation between RM, log P and the numerical values of the topological indices. By suitable transformations of the equations obtained it was possible to derive new correlation equations enabling the calculation of topological indices which could be used in the formulation of rules for the analytical identification of the compounds studied.

J. Chromatogr. 303, 190-192 (1984). Study of the masking effects of silica, impregnated with amino acids, nucleic acid bases, and organic acceptors, on "charge-transfer" TLC behaviour of pyrene. Discussion of the interaction between the impregnant and pyrene, between silica and pyrene and between silica and impregnant.

Detection limit 2000 ng. An empirical formula for Rf was presented as a function of atomic number and ionic radius of the separated species and developing reagent.

J. Chromatogr. 404, 307-312 (1987). Study of TLC Rf values of 8 pairs of facial and meridional isomers of cobalt (III) and chromium (III) complexes on silica with 21 solvent systems. Discussion of the elution order with varying solvent systems and comparison of the results with those obtained by PC. Consideration of the possible mechanism for the separation of the isomers.

J. Chromatogr. 469, 121-126 (1989). Study of the lipophilic character of a series of ß-carbolines by reversed-phase TLC. Comparison of the Rm values with those obtained by HPTLC. Discussion of the effect of pH on the Rm values. Good linear relationship between Rm values and the classical log p values obtained with an octanol - water system.

J. Planar Chromatogr. 5, (1992). General aspects of practical thin-layer chromatography: Choice of sorbent, characterization of the sorbents including explanation of meanings of code letters and numbers in product designations, storage and stock-holding as well as areas of application.
