TLC of 2-styrylquinolines on silica with 1) benzene - ethyl acetate 8:2, 2) benzene - acetone 9:1, 3) benzene - methanol 19:1. Detection by spraying with Dragendorff’s reagent. Investigation of the relation between the quantity and spot area for quantification using a computer correlation analysis.

J. Chinese Herb Med. (Zhongcaoyao) 27, 275-277 (1996). TLC of scopoletin in Dinggongten, Erycibe obtusifolia Beuth on silica with benzene - ether 1:1. Identification by comparison with the standard under UV 365 nm. Quantification by fluorescence spectrophotometry at 347/>420 nm after elution. Discussion of the suitability of the method for the purpose.

J. Planar Chromatogr. 10, 348-352 (1997). Development of a simple, rapid and reliable TLC method for the identification and quantification of 11-nor-D9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH) in urine. HPTLC on silica gel 60 WRF254s layers (0.1 mm layer thickness) with dichloromethane - hexane - methanol 7:2:1. Because the chromatograms were evaluated directly by HPTLC-UV and HPTLC-FTIR on-line coupling, it was not necessary to derivatize with fast blue salts or other health-endangering azo dyestuffs. The validated detection limits for THC-COOH (UV: 4 ng/mL, IR: 14 ng/mL) enabled qualitative and quantitative evaluation in the region of the 20 ng/mL cutoff.

Anal. Letters 31, 475-489 (1998). HPTLC of plant tissues, dansylated in a microwave oven, on silica with chloroform - triethylamine 2:1. Quantitation by in situ densitometry at 338/>502 nm. Detection limit 1.8 - 3.0 ng. Precision 0.75-1.39%.

J. Planar Chromatogr. 13, 257-260 (2000). Description of the combined use of overpressured layer chromatography with digital autoradiography for qualitative and quantitative determination of metabolites depending on the complexity and radioactivity content of the matrix investigated. OPLC of extracts of metabolite solutions on HPTLC silica gel layers. Detection by autoradiography.

Proc. Intern. Symp. on Planar Separations Plan. Chrom. 149-152 (2003). Description of an on-line system which provides computer controlled elution of spots from the TLC plate and injection of the eluted substances into MS. All flexibility of TLC is retained, small fraction of MS working time is needed, and any spot on an unlimited number of plates can be selected.

LC-GC Europe 16, Issue 4, 225-229 (2003). A technique for the direct determination of substances from TLC plates by MALDI-MS is discussed. Methods for the generation of quantitative data by adding an internal standard to the development solvent are described and the use of post-source decay-MALDI experiments in conjunction with TLC-MALDI-MS for compound identification is reported.

J. Liquid Chromatogr. 6, 1213-1220 (1983). TLC of benzo(a)pyrene, dimethylbenzanthracene, pyrene on Silica with benzene - hexane 1:9. Detection by UV. Micropreparative elution with ELUCHROM elution system; subsequent investigation by IR-spectroscopy.
