Our CCBS database includes more than 11,000 abstracts of publications. Perform your own detailed search of TLC/HPTLC literature and find relevant information.
The Cumulative CAMAG Bibliography Service CCBS contains all abstracts of CBS issues beginning with CBS 51. The database is updated after the publication of every other CBS edition. Currently the Cumulative CAMAG Bibliography Service includes more than 11'000 abstracts of publications between 1983 and today. With the online version you can perform your own detailed TLC/HPTLC literature search:

J. Planar Chromatogr. 15, 418-424 (2002). Investigation of the effect of electric fields on mobile phase migration velocity and on the retention of chromatographed solutes for so-called horizontal electric fields with samples applied at the anode and cathode end of the plates. TLC of polycyclic aromatic hydrocarbons and quinoline derivatives on silica gel, alumina, silanized silica gel, RP-18, polyamide and cellulose with n-hexane, n-heptane, carbon tetrachloride, methylcyclohexane, ethyl methyl ketone as well as the binary mobile phase carbon tetrachloride - ethyl methyl ketone in different proportions.
IV. Thin-layer chromatography on silica of simple and complex organic compounds. J. Liq. Chrom. Rel. Technol. 27, 2003-2018 (2004). The LSChrom software was applied to organic compounds with simple and complex structure being cis or trans olefinic derivatives and substituted tetrahydroisoquinolines, respectively. Lists of recommended mobile phase were obtained, avoiding any preliminary trial and error experiments. The procedure is based on the structure of any compound, literature data for adsorption properties of the relevant groups available in the structure, and numerous calculations. The experiments with 12 arbitrarily selected eluents showed, for about 150 measurements, the proper retention of any compound and good separation of the cis-trans isomers.
J. Planar Chromatogr. 24, 274-280 (2011). Presentation of new reagents and visualization methods which enable the detection of particular substances. The best of them provide high selectivity and low detection limits and lead to a reliable analysis of the developed chromatogram. Three groups of chemical reactions are used for detection: oxidation, reduction, and complexation, as well as precipitation of colored precipitates. Oxidation and reduction are most widely used due to their selectivity, which allows detection and identification of the separated substances. Like this the target substance can be selectively visualized, as for example antioxidants in complex natural matrices. Innumerable chemical, physical, and biological methods of visualization are known. Required are new, more efficient reagents fo a selective visualization of a defined part of a substance or, in some cases, for a specific determination of a specific substance. The article describes the detection of food ingredients, medicines and pharmaceuticals, organic compounds not present in food, and inorganic compounds.
J. Chromatogr. 341, 426-431 (1985). TLC of the fluorescent derivatives formed from primary or secondary alcohols and 3-chloroformyl-7- methoxycoumarin on silica with benzene - ethyl acetate 8:2. Rf values and detection limits for several alcohols were given. 1) HPLC method was also described, 2) 17-oxosteroids were determined in urine from normal humans after enzymic hydrolysis, extraction, and derivatization with 3-chloroformyl-7-methoxycoumarin.
J. Chromatogr. 435, 210-218 (1988). TLC on silica, sprayed with spore suspension after application. Chromatography with chloroform - acetone 85:15. Detection limit, 10-30 ng. Evaluation by estimating the size of spots with no fungal growth.
J. Planar Chromatogr. 3, 307-310 (1990). The liquid crystalline method for the visualization of thin layer chromatograms involves mapping the chromatogram by transferring the organic substances from the plate to a liquid crystal layer. Because the properties of the substrate have no significant influence on the transfer of the substances to be mapped it should be possible to use liquid crystal detectors to detect substances adsorbed on any substrate, can be used to visualize spots mapped from carbon layers. Method demonstrated with toxic substances used in warfare (o-ethyl-s-diisopropylaminoethyl ester of methanephosphoric acid) pesticides.
J. West China Univ. Med. Sci. (Huaxi Yike Daxue Xuebao) 24, 194-197 (1993). Presentation of a novel stable fluorescent reagent CGE(N) for the detection of compounds containing amino groups with TLC detection of glucine as example. Fluorescent excitation at 277 nm and emission wavelength of the spot at 356 nm, resp. Detection limit of 240 ng/spot.
Chromatographia 48, 548-554 (1998). Study of double spray in TLC to enhance fluorescence of dansyl derivatives, 200-360 fold by spraying with 20% triethanolamine in propane-2, followed by 30% paraffin oil in hexane, spots are stable for one month. Visual detection limits, 1-6 p mole per spot. Use of the graphical method to explain the phenomena.
