Thin-layer chromatography (TLC) was originally developed by Nikolai Izmailov and his postgraduate student Maria S. Schreiber as early as 1938. It was basically used to replace the time-consuming column chromatography so as to obtain faster results; in addition, it required less sample. Berezkin (1995) speaks of the history of planar ... Webrelative thin layer chromatography (TLC) are still very important methods used today. Since 1950, new methods called gas chromatography (GC) and high pressure/performance liquid chromatography (HPLC or LC) have been introduced which are even more important. The theory and practice of GC and HPLC are introduced in Chemical Instrumentation courses. sushi in brush co
