WebThin Layer Chromatography (TLC) is a technique used to analyse small samples via separation. For example, we could separate a dye out to determine the mixture of dyes in a forensic sample. There are 2 phases involved in TLC - stationary phase and mobile phase. Stationary phase. WebThin 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 … WebThin 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. atl baseball stadium
