J. Liquid Chromatogr. 8, 3017-3031 (1985). TLC separation of metal nitrates, chlorides or sulfates on titanium arsenate layers using different solvents (e.g. 0.1 M oxalic acid, 0.1 M citric acid, 0.1 M tartaric acid). Detection by conventional spot test reagents.

J. Liquid Chrom. 10, 3623-3636 (1987). TLC of herbicides and plant growth regulators on calcium sulfate by sequential TLC with acetone, benzene, CCl4, chloroform, ethyl acetate, dioxane, propanol. Detection by spraying with 1% ethanolic alkaline bromophenyl blue solution.

J. Liquid Chromatogr. 12, 3163-3191 (1989). Examination of the chromatographic behavior of 14 heavy metals on silica and silica impregnated with aqueous salt solutions of NaCl, KBr, KI and NH4Cl (0.1 and 1.0 M) using solutions of formic acid and aqueous salt solutions in various proportions. Achievement of quantitative separations of µg to mg quantities of Ti(IV), Fe(III) and Al(III) from each other in addition to a series of effective qualitative separations of binary and ternary mixtures. The development time for the migration of mobile phases was much shorter on NH4Cl-impregnated silica layers. More compact and clearer detection of cations was observed on KI-impregnated silica layer.

J. Planar Chromatogr. 2, 277-279 (1990). HPTLC of PTH-alanine, PTH-glycine, PTH-tyrosine on 3 µm silica gel with methylene chloride, acetonitrile 20:1 as mobile phase. Quantification by densitometry. Results: Separation times are longer than or similar to those of conventional HPTLC plates with 5 µm particle layers. Separation performance for the 3 µm particles is less than that of convention HPTLC plates. The layers are, however, prepared by different manufacturers and are not necessarily of similar coating density, binder, particle size distribution, particle shape etc.

J. Chromatogr. 603, 223-229 (1992). Use of porous glass sheet as stationary phase for TLC of inorganic cations. Some cations gave rise to fluorescent compounds when spots on the sheet were heated for detection. 20 fluorescent cations were screened from commercially available reagents by heating at various temperature from 100 - 700 °C for 15 min. Investigation of the detection limits. Discussion of the in-situ fluorescence spectra.

Chromatographia 40, 96-98 (1995). Study of the behavior and separation ability of cellulose, starch and aminoplast thin-layers with aqueous and non-aqueous mobile phases by measuring the retention of a homologous series of benzamides. Discussion of the retention behavior and separation ability in terms of the nature of the solute, support and eluent.

J. Planar Chromatogr. 10, 18-25 (1997). Study of the distribution of different ion-pairing reagents, e.g. tetramethylammonium (TMA), tetrabutylammonium (TBA), cetyltrimethylammonium (CTMA), and trioctylmethylammonium (TOMA) by measurement of the absolute concentrations of the compounds in the stationary phase after chromatography (OPLC) on silica impregnated by immersion into a methanolic solution (0.05 M) of the reagents with methanol - water mixtures in different ratios. The behavior of acidic, neutral, and basic compounds were studied simultaneously. The chromatographic results showed good correlation with the concentration of the reagents measured on the layer.
