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. 21, 129-134 (2008). TLC of racemic metoprolol, propranolol, carvedilol, bisoprolol, salbutamol, and labetalol on silica gel impregnated with optically pure L-Glu with acetonitrile - methanol - water - dichloromethane 10:3:1:2 or 10:3:3:2 (for propanolol), and on silica gel impregnated with L-Asp, with acetonitrile - methanol - water - dichloromethane 5:3:1:3, or acetonitrile - methanol - water - glacial acetic acid 50:10:5:7. Detection with iodine vapor; the detection limits were 0.23, 0.1, 0.27, 0.25, 0.2, and 0.2 µg for each enantiomer, respectively.

J. Chromatogr. A 1218 (19), 2737-2744 (2011). Investigation of new cellulose tribenzoate/gypsum layers in the ratio up to 8:1 (w/w) for the chiral resolution of closely related aromatic ketones (e.g. tetralones and indanones), alcohols (e.g. benzhydrols) and racemates or enantiomers of other compound classes (e.g. dinitrophenyl amino acids). 16 racemates were baseline or partially resolved by eluting with methanol or 2-propanol/water mixtures on 4:1 (w/w) layers among 22 investigated compounds. The study provided better understanding of the retention and resolution mechanisms on this chiral stationary phase, however, some results were unexpected and confirmed the complexity of enantioseparation mechanisms. Evidence from experimental tests is necessary. Quantification of the investigated compounds by densitometry in the visible region of cellulose tribenzoate/gypsum plates after their exposure to iodine vapours.
