Daicel Zwitterionic Columns
Daicel expanded its extensive portfolio of immobilized columns to include CHIRALPAK® ZWIX(+) and CHIRALPAK ZWIX(-), two columns packed with novel zwitterionic chiral stationary phases(CSPs). TheCHIRALPAK ZWIX columns were developed for separation of a great variety of zwitterionic molecules, specifically, for separation of underivatized amino acids, although customers are reporting many successful separations on other difficult-to-separate analytes as well.
ZWIX selectors are zwitterionic molecules that incorporate both anion- and cation-exchange functional groups. These novel ZWIX selectors exhibit exceptional enantioseparation capabilities toward zwitterionic molecules such as amino acids and small peptides.
