Chiral columns, ChiraDex®

Supplier: Merck

ChiraDex® is a versatile HPLC column characterised by broad enantioselectivity and can be used for the separation of enantiomers of numerous different classes of substances. ChiraDex® is based on beta-cyclodextrin covalently linked to spherical particles of silica, and is ideal for chiral separation of hydrocarbons, steroids, phenol esters and derivatives, aromatic amines, heterocycles with five- to seven-membered ring. Simply composed RP-eluents can be used in most separations.
