J. Planar Chromatogr. 7, 117-121 (1994). HPTLC and TLC of amino acids, sugars, cardiotonic heterosides on silica with common eluents. Derivatization by pressing a pad of polymeric foam containing the reactive solution on to the chromatographic plate in order to obtain homogeneous and complete distribution of the reagent over the whole plate. Comparison with spraying and dipping.

J. Planar Chromatogr. 16, 23-27 (2003). TLC of a zinc complex stock solution (Zn(CH3CH2COO)2(tu)2 - a complex of zinc butyrate bound to two thiourea molecules) on RP-18, aluminium backed, with methanol - water 2:3. The first interface was formed by vacuum deposition of silver on to the chromatographic layer and onto a channel formed by scraping the layer from the glass plate. The unmodified aluminium backing of a TLC plate (again formed by elution) was used as the second interface. Silver vapor-coated aluminium gave better results.

J. Liquid Chrom. 5,1567-1572 (1982). Description of a new detector system for continuous-flow TLC providing possibilities both for optical and electrochemical measurements with low detection limits.

J. High Resol. Chromatogr. 6, 575-576 (1983). Two-dimensional TLC of saturated and cis-and trans-monounsaturated alcohols, fatty acids and fatty acid methylesters on silica impregnated with AgNO3, H7[P(W2O7)6] + Co(NO3)*6 H2O with 1.) toluene -hexane - isopropanol - acetic acid 30:30:1:0.3 for 2 cm, 2.) toluene - ethyl acetate - acetic acid 20:1:0.2 for 3.5 cm. Detection by heating at 220-250 °C. Densitometry.

I. Overpressured thin-layer chromatography. J. Chromatogr. 290, 127-1 34 (1984). Study of over-pressurized thin-layer chromatography in ion-pair systems. The most important aspect when a reversed-phase ion-pair TLC system is to be used is to apply a suitable procedure for pre-treatment of the sorbent. The sorbents were pre-treated by immersion in an ethanolic solution of ion-pair reagent, cetrimide being used as the ion-pairing agent and different carboxylic acids and phenols.

J. Planar Chromatogr. 6, 341-345 (1993). Use of color slide films for the selection of appropriate filters and exposure data. Color prints are then made with color negative film using the previously optimized condition. With this method the number of photographs can be limited to one of each chromatogram. TLC of steroids (hydrocortisone, prednisolone, mesylate, hydrocortisone acetate, and spironolactone, trenbolone acetate, hydroxyprogesterone caproate, pregnadienolone acetate oxime ) with benzene - ethyl acetate 1:1. Visualization by spraying with a 10% ethanolic solution of sulfuric acid, followed by heating at 100 °C for 2 to 4 min.

Chromatographia 20, 223-227 (1985). Study of the overloaded systems of heptane + methylene chloride - silica using an equilibrium sandwich chamber for continuous TLC and dye mixtures as the model samples. Investigation of the effect of sample concentration and volume on the maximum separation yield. Illustration of band compression effects for samples dissolved in solvents having a low eluent strength.

J. Sliwiok (ed.): Acta Chromatographica 10, 85-96 (2000). Investigation of chemically bonded stationary phases using Raman spectroscopy to determine the density of coverage of the inorganic silica matrix with organic ligands. Comparison of Raman spectra obtained by irradiation with a high-power neodymium laser and a low-power argon-krypton ion laser.
