Chem 211

Thin Layer Chromatography (TLC) is a solid-liquid technique in which the two phases are a solid (stationary phase) and a liquid (moving phase) Solids most commonly used in chromatography are silica gel (SiO 2 x H 2 O) and alumina (Al 2 O 3 x H 2 O) Both of these adsorbents are polar but alumina is more so
