Thin Layer Chromatography

In thin-layer chromatography, the adsorbent is a relatively thin, uniform layer of dry, finely powdered material applied to a glass, plastic, or metal sheet or plate, glass plates and aluminum plates being most commonly employed. The separation achieved may be based upon adsorption, partition, or a combination of both effects, depending on the particular type of stationary phase, its preparation, and its use with different solvents. General Testing Procedure, Procedure, chromatography, thin layer chromatography
