J. Chromatogr. Sci., 26, 325-330 (1988). Investigation of the chromatographic behavior of inorganic ions on Sephadex G-25 with acetone - water mixed eluent system in TLC and CC. Emphasis on the effects of eluent electrolyte and of the solvent compositions inside and outside the gel beads. Evaluation of the partition effect on the retention mechanism for different salts. Proposal of a theoretical model interpreting the effect of the background eluent ions on the capacity factors of the analyte ions.

Thin-layer chromatographic retentions on silica of some (E)- and (Z)-oxazolones and related cinnamates as a function of mobile phase effects or Hammett constants. J. Chromatogr. 545, 161-175 (1991). Study of the TLC behavior of 20 diastereoisomeric 1,1-disubstituted 2-arylethenes [(Z)- and (E)-oxazolones and - cinnamates] on silica with 40 mobile phases. Correlation and discussion of the relative retentions and the retentions themselves with solvent selectivity effects of Hammett constants of the various substituents on the aryl group.

2. Experimental condition affecting resolution and Rf value.) (Japanese). Kagaku to Kyoiku (Jap. J. Sci. & Educ.) 43 (3), 178-181 (1995). Demonstration of the effect of the experimental conditions, such as pre-saturation, developing distance, developing solvent system, and the stationary phase, on the degree of resolution and Rf value in TLC analysis.

CBS 81, 2-5 (1998). The performance and reliability of result of both procedures is comparable - HPTLC being slightly better than HPLC. For the assay of phospholipids in pure substances, pharmaceutical products and lecithin HPTLC is more cost efficient than HPLC by a factor of 2.5.

An in vivo study. Polish Journal of Pharmacology and Pharmacy 39, 379-386 (1987). TLC of imipramine, desipramine and their 2-hydroxy homologues on silica with chloroform - isopropanol 10:1, intermediate drying and isopropanol - chloroform - water - 25 % NH3 50:30:20:2; localizing spots under 254 nm UV after spraying with water; quantification by spectrophotometry after elution. Determination limit 0.5 µg/sample.

J. Planar Chromatogr. 5, 441-445 (1992). Extension of the applicability of a new retention model published before (T. Kowalska, J. Planar Chromatogr. 2, 44-48 (1989)) to reverse phase chromatography with THF - water and acetone - water eluents. For the solutes considered, good agreement was found between experimental retention parameters (Rf) and those predicted by the derived models. The results of the computations performed enabled conclusions to be drawn concerning the mechanism of retention of test solutes (PAHs) in the chromatographic systems investigated.

J. Planar Chromatogr. 13, 254-256 (2000). Study of the physicochemical fundamentals of planar analytical test methods with analytical reagents forming poorly soluble products on reaction with the target compound. In the test methods the analytical reagent was applied to a porous planar system (paper, or an adsorbent layer spread on a support). It was shown that regularities in the planar test methods are similar to those observed in planar chromatography.

Chromatographia, 72(11-12), 1169-1176 (2010). Experimental and theoretical study of the adsorption kinetics of the gas phase of solvents most often used in TLC (methanol, acetic acid, ethyl acetate, toluene, chloroform, and acetone) in the N-chamber (the chamber most often used for analytical TLC, in 95 % of publications). To describe the kinetics an equation is proposed, which relates the solvent vapor adsorption to the time, the vapor pressure in saturated chambers and the diffusion coefficients of the solvents. It was found that as the characteristics of the adsorbent layer substantially improved by the manufacturers, the weight of mobile phase adsorbed by plates has increased several fold.
