Thin layer chromatography (tlc) thin layer chromatography is similar to paper chromatography, but the stationary phase is a thin layer of a solid such as alumina or silica supported on an inert base such as glass, aluminum foil or insoluble plastic the mixture is ‘spotted’ at the bottom of the tlc plate and allowed to dry the plate is. Thin layer chromatography (tlc) tlc is a simple, quick, and inexpensive procedure that gives the chemist a quick answer as to how many components are in a mixture tlc is also used to support the identity of beaker with filter paper cover the beaker with a watch glass, swirl it gently, and allow it to stand while you prepare your tlc plate.
