www.ucl.ac.ukAdsorption chromatography The stationary phase is a solid on which the sample components are adsorbed. The mobile phase may be a liquid (liquid-solid chromatography) or gas (gas-solid chromatography); the components distribute between two phases through a combination of sorption and desorption processes. Thin-layer chromatography (TLC)
