J. Chromatogr. Sci., 30, 192-196 (1992). The method is demonstrated with seven naphthalene compounds, four PAH’s and some other thermally stable substances.

J. Planar Chromatogr. 2, 53-61 (1989). Construction of the new instrument with the principle of five rotation planar chromatographic methods. The efficiency of the RPC methods demonstrated with the separation of saponin glycosides from Panax ginseng and some furocoumarin isomers from Pastinaca sativa. For preparative separation, an extract from Peucedanum palustre was chosen.

J. Planar Chromatogr. 28, 126-132 (2015). TLC of 17 morphine derivatives on RP phase with 3 different mobile phases, (1) methanol - 0.02 M ammonium hydroxide, (2) methanol - 0.7 M ammonium hydroxide, and (3) methanol - 0.02 M acetic acid. In each case, the individual mobile phases contained 30-90 % (v/v; in 10 % increments) of methanol as an organic modifier. Detection by absorbance measurement at 254 nm. RP-TLC can be used for the characterization of the lipophilicity of semisynthetic derivatives of morphine.

J. Chromatogr. 500, 661-671 (1990). Development of a system making color reactions on TLC plates amenable to computer handling. Identification of unknown substances using corrected Rf values and color reactions by means of computerized retrieval from large data base, based on a series of four color reactions carried out in sequence on the same spot and by numeric encoding of the observed color with a color reference chart. Comparison of the identification power with that of GC. GC retention indices and UV absorption maxima can also be introduced in the identification program. Use of a single TLC system with color reactions provides about the same identification power as a single GC system and can be increased by using two or more different TLC systems in parallel.

J. Planar Chromatogr. 27, 420-427 (2014). HPTLC and TLC of fatty acids and polyphenols in plant extracts of raspberry (Rubus idaeus), strawberry (Fragaria ananassa), blackcurrant (Ribes nigrum), aronia (Aronia Medik.), Japanese rose (Rosa rugosa Thunb.) seeds, and palmetto palm (Sabal minor) fruit on silica gel or RP-18 with different micellar mobile phases containing cationic cetyltrimethylammonium bromide (CTBA), or anionic sodium dodecyl sulfate (SDS), or nonionic polioxyethylene (23) lauryl ether (Brij35).

Chromatography the State of the Art, Vol. I, Akademiai Kiado, Budapest 1985, 467-492. Considerations on where to use GC, TLC, HPLC. When TLC appears appropriate, suggested sequence: conventional silica using 6 solvent systems, then water resistant silica with 3 aq. solvent systems, then HPTLC material for optimization. Finally, optimized system adopted for OPTLC technique.

Chinese J. Pharm. Anal. (Yaowu Fenxi Zazhi) 10, 274-276 (1990). Thin-layer electrophoresis of human serum albumin on acetyl cellulose. Determination by densitometry at 595 nm. CV 0.05 – 0.23%.

J. Liquid Chromatogr. 15, 1655-1663 (1992). TLC of lipid classes on silica with petrol ether - toluene 8:2, 8 cm, and chloroform - acetone 95:5, 18 cm. Detection under UV 254 nm. Identification by co-chromatography against authentic samples. Semi-quantification by GC after elution with chloroform - methanol 1:1.
