ResourceThin layer chromatography
The technique of Thin Layer Chromatography (TLC) is normally used as an analytical method to follow the progress of a reaction, to analyse mixtures or to establish conditions for a preparative separation of compounds using column chromatography. The stationary phase (often silica) is coated on plastic or aluminium plates. The ...
