Chiral Technologies: CHIRALPAK

CHIRALPAK Zwitterionic phases


CHIRALPAK ZWIX(+) and CHIRALPAK ZWIX(-) are newer additions to the portfolio of immobilised phases. The CHIRALPAK ZWIX chiral selectors are zwitterionic molecules that incorporate both anion- and cation-exchange functional groups. These 3um phases were developed specifically to exhibit stereoselectivity for zwitterionic molecules, such as underivatised amino acids and peptides. As the two ZWIX chiral selectors are pseudo enantiomers, the elution order of amino acid enantiomers can be reversed by using either the ZWIX(+) or ZWIX(-) selector. Typically, L-enantiomers elute first from a CHIRALPAK ZWIX(+) column.
