Proc. Intern. Symp. on Planar Separations Plan. Chrom. 423-432 (2003). TLC of 2,4-dichlorophenoxyacetic acid, 2-methyl-4-chloro-phenoxypropionic acid, 2,4-dichloropropionic acid, and 2,4-dichlorobutyric acid on precoated silica gel plates and silica gel, prewashed, and impregnated with Cu(II), Co(II) and Fe(III) salts with heptane - dioxane - acetic acid 60:40:1. Visualization of spots on precoated plates under UV 254 nm. The best results have been achieved with silica gel impregnated with 0.2 % CuSO4. In addition to efficient separation, such impregnation makes possible visualization without further use of reagents or UV lamps. New method for separation and identification.

J. Planar Chromatogr. 23, 18-22 (2010). TLC of amphotericin B on silica gel with chloroform - methanol - borate buffer (pH 8.3) 4:5:1 in a chamber pre-saturated for 20 min. Detection under UV 366 nm. The hRf of the main component was 46, and of the minor component 31. Quantitative determination by absorbance measurement at 385 nm. Direct bioautography with Candida albicans proved to be the most sensitive method, with a detection limit of 0.8 ng per spot. For densitometric evaluation of plates at 385 nm ten times more substance is required.

J. Chromatogr. 642, 249-260 (1993). Review of chromatographic methods, with 14 references related to TLC.

J. Agric. Food Chem. 49, 2352-2358 (2001). TLC of metalaxyl (N-(2,6-dimethylphenyl)-N-(methoxyacetyl)-DL-alaninate) and metabolites on silica gel with ethyl acetate - 2-propanol - water 65:23:12. Measurement of the radioactive zones with a Bio-Image Analyzer.

Lipids 17, 650-655 (1982). For preparative separation silica plates were used with hexane - ether 6:4. For separation of hydrogenated oils into their various components, multiple development (4 or 5x) TLC was carried out with ether - benzene 1:99 followed by ether - benzene 3:97. Analytical TLC components were visualized by charring with sulfuric acid-dichromate or with iodine vapors. reparative TLC: bands were located by spraying with ethanolic dichlorofluorescein, followed by viewing under UV. The components of the seed oil of trewia nudiflora and mallotus phillipinensis were chromatographed and compared.

J. A. O. A. C. 72, 512-514 (1989). TLC of 4 synthetic pyrethroids with a-cyano ester groups on silica with 6 different solvent systems. Detection by spraying with sodium hydroxide solution, p-nitrobenzaldehyde, o-dinitrobenzene solution, successively. Detection limits 0.1 µg.

J. Planar Chromatogr. 8, 160-161 (1995). TLC of the pyrethroid insecticides fenvalerate, cypermethrin, and deltamethrin on silica with petrol ether - ether 9:1. Detection after drying by successively spraying with 1% cobalt acetate and 5% sodium hydroxide, followed by spraying with 0.1% o-tolidine reagent after 5 min. Detection limit 10 µg.

CBS 90, 12-13 (2003). TLC of oxazoline Ia on aluminum sheets RP-18 with methanol over 10 mm, followed by water - acetonitrile 1:1 over 55 mm. Ion pair chromatography of oxazoline Ia with phosphate buffer - acetonitrile 1:1 over 60 mm after dipping in 2 mM cetyltrimethylammonium bromide. TLC of oxazoline Ib and Ic with phosphate buffer - acetonitrile - dioxane 4:3:3 over 65 mm. Determination by absorbance measurement at 200 nm (oxazoline Ia and Ib) and 262 nm (oxazoline Ic) respectively.
