Radial chromatography (original) (raw)

Radial chromatography is a form of chromatography, a preparatory technique for separating chemical mixtures. It can also be referred to as Centrifugal Thin-Layer Chromatography. It is a common technique for isolating compounds and can be compared to column chromatography as a similar process. A common device used for this technique is a Chromatotron. Here the solvent travels from the center of the circular chromatography silica layered on a plate towards the periphery. The entire system is kept covered in order to prevent evaporation of solvent while developing a chromatogram.
