  • Title: Polysaccharide-derived chiral stationary phases in capillary electrochromatography enantioseparations.
    Author: Zhang Z, Zou H, Ou J.
    Journal: Methods Mol Biol; 2013; 970():457-67. PubMed ID: 23283796.
    Abstract:
    Capillary electrochromatography (CEC) has been shown to be a promising technique for miniaturized enantioseparations. Here we present the preparation and application of positively charged cellulose derivative-based chiral stationary phases (CSPs) for the CEC separation of enantiomers. The cellulose derivatives were chemically immobilized onto diethylenetriaminopropylated silica gel using tolylene-2,4-diisocyanate as a spacer. The separation of enantiomers in CEC can be performed on the positively charged CSPs with nonaqueous and aqueous mobile phases.
