Hichrom - Chiral Columns Datasheet

Hichrom manufactures two ranges of ‘Pirkle-type’ columns for the analysis of a wide range of enantiomers of pharmaceutical or agrochemical origin. CHIRA-chrom 1 type columns contain a stationary phase in which the hydroxyl groups on the silica surface have been modified by a nitrobenzoyl derivative of an optically active amino acid. In the CHIRA-chrom 2 type columns a chiral dinitrophenyltartramide moiety is bonded to the silica surface through a propyl spacer group.
