Chiral columns are designed for the analysis of a wide range of enantiomers of pharmaceutical and agrochemical origin. This column contains a chiral dinitrophenyltartramide moiety is bonded to the silica surface through a propyl spacer group.

• Chiral Pirkle-type
• High efficiency and unique covalent bonding
• Enantiomer order elution inversion

Substitution of L-phenylglycine for D-phenylglycine, the order of elution of the chiral peaks can be reversed. This can be useful in assigning peak identity or ensuring prior elution of the minor enantiomer, thus allowing its more accurate determination.
