WebChiral column chromatography is a variant of column chromatography that is employed for the separation of enantiomers, e. g. in racemates. The stationary phase contains a single enantiomer of a chiral compound. The chiral stationary phase can be prepared by attaching a chiral compound to the surface of an achiral support such as silica gel.
