- Thin layer chromatography

Thin layer chromatography (TLC) is a chromatography technique used to separate chemical compounds ^[1]. It involves a stationary phase consisting of a thin layer of adsorbent material, usually silica gel, aluminium oxide, or cellulose immobilised onto a flat, inert carrier sheet. A liquid phase consisting of the solution to be separated is then dissolved in an appropriate solvent and is drawn up the plate via capillary action,
