Thin Layer Chromatography - Chemistry LibreTexts

Thin layer chromatography (T LC) is a chromatographic technique used to se parate the components of a mixture using a thin stationary phase supported by an inert backing. It may be performed on the analytical scale as a means of monitoring the progress of a reaction, or on the preparative scale to purify small amounts of a compound.
