thin-layer chromatography


thin-layer chromatography
(TLC)
   A procedure for separating compounds by spotting them on a glass plate coated with a thin (about 0.01 inch) layer of silica or alumina, and “developing” the plate by allowing a solvent to move upward by capillary action. TLC is especially useful for identifying and comparing materials which are highly colored or which fluoresce under ultraviolet light. TLC is used extensively in explosive analysis and in the comparison of gasoline dyes, inks and various drugs.
