Theory and Mechanism of Thin-Layer Chromatography

WebbThin Layer Chromatography is a solid-liquid technique in which the two phases are a solid or stationary phase and a liquid or moving phase. The most commonly used solid phases in chromatography are silica gel and alumina. The solid phase materials are also called adsorbents due to their physical properties. However, both materials are polar. Webb1 jan. 2013 · Theory TLC is a type of liquid chromatography in which the mobile phase is liquid and the stationary phase is a thin layer of material on top of a flat plat. This layer of material is known as the sorbent. The mobile phase is known as the developing solvent, and it transports the solutes through the stationary phase.
