Economic separation of selected enantiomers: ChiraSep® DNBPG is a highly economic HPLC column for the separation of enantiomers with electrons. ChiraSep® DNBPG is a “Pirkle-phase” with R-(-)-N-(3,5-dinitrobenzoyl)phenylglycin as chiral selector and is excellently suited for the chiral separation of pharmaceutical, pesticides and flavours. For separations of enantiomers on ChiraSep® DNBPG, normal phase eluents are used; binary or ternary mixtures of a hydrocarbon (e.g. n-hexane) and organic modifier (e.g. 2-propanol, acetonitrile) have been proved as well suited. The enantioselectivity of ChiraSep® DNBPG is clearly depended on the composition of the mobile phase.
