J. Planar Chromatogr. 4, 204-206 (1991). Description of a method for the separation of enantiomers using TLC on RP phases (C-2 and C-18) with acetonitrile – water and hydroxypropyl-ß-cyclodextrins as chiral mobile phase additive for the separation of several derivatized amino acids. Detection under UV 254 nm.

J. Planar Chromatogr. 6, 357-361, (1993). Use of forced flow TLC to characterize the kinetic properties of precoated silica gel plates. The properties determined include porosity, apparent particle size, flow resistance, and the relationship between reduced plate height and reduced velocity (Knox equation). Need for layers with a greater range of pore diameters to facilitate the separation of analytes with a molecular weight greater than 500.

J. Planar Chromatogr. 8, 292 - 299 (1995). Determination of the efficiency of a variety of techniques used for the impregnation of silica gel layers with tetramethylammonium bromide (TMA), tetrabutylammonium bromide (TBA), cetyltrimethylammonium bromide (CTMA), and triocetylammonium bromide (TOMA). The absolute concentrations of the different ion-pairing reagents on the layers were measured by spectrophotometry, potentiometry, and thermogravimetry. - Impregnation of silica gel layers by plate development (normal unsaturated chamber, twin-trough chamber, overdevelopment, sandwich chamber, OPLC) and by dipping (horizontal, vertical ).

Biomed. Chromatogr. 11, 280-285 (1997). Discussion of impregnation of methods of impregnation of thin-layer materials with a variety of reagents and the role of impregnating reagents in resolving compounds on the layers with special reference to main/basic approaches of impregnation as applied to direct enantiomeric resolution. Discussion of advantages of TLC over other chromatographic methods in efficiency and quantitation. TLC may serve as method for daily routine process in various laboratories to determine enantiomeric purity with a great ease and speed, and serve as pilot methods for large scale separation of therapeutics etc.

J. Planar Chromatogr. 14, 378-383 (2001). Report of experimental results relating to the thermal instability of selected alkyl chemically bonded stationary phases as a result of their irradiation with a high-power neodymium laser, the light source of a Raman spectrometer used for the investigation. The results reported furnish a convincing confirmation of earlier intuitions, described as "vague speculations about the possible aromatization of these ligands".

J. Planar Chromatogr. 18, 160-163 (2005). TLC of rare earths (La(III), Ce(III), Pr(III), Sm(III), Gd(III), Er(III)) on silica gel and silica gel impregnated with 2.5 M ammonium nitrate with different mixed mobile phases containing di(2-ethylhexyl)dithiophosphoric acid as a complexing agent. The best results were obtained by use of ethyl methyl ketone - tetrahydrofuran - 1 M di(2-ethylhexyl)dithiophosphoric acid 17:8:1. Double development was used to obtain better separation of consecutive rare earths.

J. Planar Chromatogr. 1, 182- 187 (1988). Discussion of sample application in planar chromatography involving fundamentals, negative aspects, systematic errors, accuracy, precision, working range, coupling to other techniques and the practical solution.

Proc. Intern. Symp. on Planar Separations Plan. Chrom. 211-221 (2003). Description of the applications of continuous development HPTLC techniques combining on-line and off-line chromatographic principle steps (sample application, separation and detection). Fully on-line combination of off-line sample application and on-line detection as well as fully off-line methods are compared by separating Test Dye Mixture III and furocoumarin isomers. HPTLC of Test Dye Mixture III on silica gel with toluene and different compositions of toluene and chloroform mixtures 9:1, 15:3, 4:1 and HPTLC of furocoumarin isomers on silica gel with ether - dichloromethane - tetrahydrofuran - hexane 10.71:9.68:7.5:72.11, diluted with 50%, 75%, and 100% hexane. All experiments were performed in a further developed prototype apparatus. Detection by densitometry in a range of 200 -1000 nm.
