Sz. Nyiredy, A. Kakuk (eds.): Planar Chromatography 2000, Lillafüred, Hungary, 24-26 June 2000, Res. Inst. for Med. Plants, p. 205-217. TLC of cetyldimethylbenzil ammonium chloride, cetyltrimethyl ammonium bromide, tributylmethyl ammonium hydride, laurylpyridium chloride, distearyldemethyl ammonium, benziltrimethyl ammonium hydride, ATO-368, AT-196, n-dodecilamine, AT22-300 on aluminum oxide with chloroform - NH3 - methanol 8:1:1 and on silica gel G with ethyl acetate - methanol - NH3 13:3:4 up to 15 cm. TLC of other quaternary ammonium salts and tertiary amines on silica gel G with chloroform - pyridine - methanol 4:3:3 for 150 min (this was the best system for separation of quaternary ammonium salts) or 5:3:2.
XI. Thin-layer chromatographic fractionation of Ames mutagenic compounds in chlorin-treated 4-methylphenol solution. J. Chromatogr. 360, 137-159 (196(6). TLC of Ames mutagenic compounds on silica with acetone - hexane 1:1. Detection under UV light. TLC of one of the 6 fractions on polyamide with chloroform. Examination of the fractionated components for mutagenicity by means of Ames assays, and identification by GC-MS.
J. Planar Chromatogr. 11, 277-282 (1998). TLC with UV scanning densitometry has been studied as an alternative to TLC-FID for the rapid determination of aromatic, polar, and non-eluted compounds in coal-derived products. The results obtained show that TLC-UV is adequate in terms of speed, repeatability, and quantitative analysis. Preparative TLC enables isolation of fractions suitable for preparative purposes and is less time-consuming than LC methods. TLC on silica gel, developed with an optimized elution sequence, 12 min with toluene then 4 min with dichloromethane - methanol 19:1. Before densitometry the plates were dried at 120°C and stored in a desiccator for 5 min. Quantitative assessment of the content of the aromatic, polar, and noneluted fractions was carried out by scanning in the UV-VIS mode.
Indian Police Journal LVI 4, 55-64 (2009). A TLC method has been developed for checking counterfeit Indian currency using TLC scanning and photo imaging technique. For comparison, scanning of the security thread of both genuine and counterfeit 500 rupees bills was performed by multi-wavelength absorbance measurement of the entire area covering the intaglio ink portion. Fluorescence evaluation at 366 nm of both genuine and counterfeit rupee bills showed the security features of genuine bills very well. A regular, good absorbance pattern was observed on the surface of genuine bills whereas in case of counterfeit currency there was an irregular absorbance pattern. Under white light no major difference was found between genuine and counterfeit bills.
Chinese Anal. Chem. (Fenxi Huaxue) 26, 120 (1998). TLC on silica with benzene - ethyl acetate - acetic acid 240:50:3. Detection under UV 254 nm. Quantification of methyl-, ethyl-, propyl- and butyl-hydroxybenzoates by densitometry at 260 nm. Calculation of the yield for each. Detection limits 100, 100, 200, 300 ng/spot, respectively.
J. Liq. Chromatogr. Relat. Technol. 37, 2249-2257 (2014). HPTLC of benzyltrimethylammonium chloride (1), dodecyltrimethylammonium chloride (2), tetrabutylammonium bromide (3), and methyltrioctylammonium bromide (4) on silica gel with methanol - 5 % aqueous EDTA 7:3. Detection by spraying with Dragendroff reagent. The hRF values for (1) to (4) were 32, 43, 62 and 75, respectively.
J. Chromatogr. 446, 17-22 (1988). TLC of non-ionic surfactants on alumina with carbon tetrachloride - acetonitrile in various proportions. Detection by spraying with modified Burger reagent and densitometry at 500 nm. Discussion of the relationship between the length of the ethylene oxide chain and the strength of the solvent system.
