Quantitative determination of TLC-separated enantiomers. GIT Suppl. Chromatographie 3, 27-32 (1987). By means of nine examples (D-Phe, tert.-leu, 5, 5-dimethyl-thiazolidine-4-carboxylic acid, O-Bzl-Ser, L-4-iodophenylalanine, L-he, L-tyr, L-methyldopa, D-leu-L-leu) is demonstrated, that the quantitative determination of TLC-separated antipodes is a useful method for daily routine process in any laboratory. The resolution of the enantiomers is excellent, the respective antipodes could be evaluated at trace levels, the limit of determination is found to be at or above 0.1 %. In comparison to the "classical methods" GC and HPLC, TLC offers separation in parallel runs.
