H. TRAITLER, A. STUDER, R.E. KAISER (eds): Instrumental HPTLC, Institute for Chromatography, Bad Dürkheim, FRG (1987), 155-165. TLC on chiral plate with methanol - water - acetonitrile 50:50:200, 50:50:30 and 50:70:200. Detection by dipping in a solution of 0.3 % ninhydrin in acetone and heating at 110 °C for 15 min. Quantification by densitometry. Detection limits, 0.1 % of the minor enantiomer.

J. Planar Chromatogr. 2, 374-377 (1989). TLC separation of glycine, alanine, valine, phenylalanine, serine and theonine on chitin with simple (monocomponent and binary) mobile phases (like e.g. 1-pentanol, 2-pentanol, 2-butanaol); discussion of theoretical elaboration of the separation conditions.

Chromatographia 30, 405-409 (1990). Investigation of the TLC behavior of 13 anions on silica and silica impregnated with copper sulfate solution, with aqueous-organic solvents containing acetone. Examination of the effect of copper sulphate concentration on the mobility of anions. Comparison of the results on two kinds of layer. Discussion of the effect of anion loading on Rf values. Change of the selectivity on impregnated layers. Aqueous sodium chloride - acetone 9:1 were the most effective solvens systems for differential migration of anions.

J. Liquid Chromatogr. 14, 1461-1467 (1991). TLC of synthetic dyes on antimonic acid and on admixture of antimonic acid and silica with butanol – acetic acid – water 5:1:2. Discussion of the separation potential of the stationary phase.

Chinese J. Chromatogr. (Sepu) 12, 35-36 (1994). Study of the use of surfactants in TLC for the separation of acid, alkaline, and water-soluble food dyestuffs and water-soluble vitamins B2, B6, B12 on silica mixed with a polymerpacking material (GDX). Mobile phase containing hexadecyltrimethylammonium bromide. Comparison of the results with those from alkyl-bonded silica layers.

J. Planar Chromatogr. 8, 323 - 326 (1995). TLC of aromatic hydrocarbons (anthracene, 9-methylanthracene, pyrene, benzopyrene, fluoranthene) and quinoline derivatives (2- and 4-hydroxyquinoline, 8-nitroquinolone, 6-methylquinoline, 7- and 8-methylquinoline) on volcanic tuff (silica containing trace amounts of metal ions determining specific interactions) after chemical treatment with silicon tetrachloride and styrene vapor with hexane, cyclohexane, benzene, ethyl acetate, acetone, dioxane, and methanol.

Acta Chromatographica 8, 32-38 (1998). Description of the synthesis and characterization of two dicationic zeolites of the type metal cation - organic cation which have been used as stationary phases in TLC. The new stationary phases were tested by TLC of a test dye mixture. TLC of methylene blue, crystal violet, rhodamine 6G, rhodamine B, and fuchsin (basic) with benzene - chloroform - methanol 6:4:1 and benzene - chloroform - methanol - acetic acid 4:3:3:1.

Chem. Environ. Res. 9 (3&4), 329-332 (2000). TLC of a dye test mixture (methyl red, methyl orange, methyl green) on "Sorbfil" layers with 2-propanol. As preliminary zone a writing, a chromatographic or a filter paper was attached to the layer. Increased efficiency due to concentrating effects on connection site. Rapid and simple method for large sample volumes or for concentrating in a flow.
