Sepax SFC-SCX Columns
Description
Sepax SFC-SCX is a silica based mixed-mode strong cation exchange phase. The phase has a mixed
chemical structure of sulfonic acid and phenyl group. The mixed mode of strong cation-exchange
and hydrophobicity offers high selectivity and high resolution separation for cationic/basic and
nitrogen containing compounds as well as desirable retention for a variety of weak cationic and
neutral organic compounds. A uniform, polymeric bonding of SFC-SCX enhances its stability under
various separation conditions.
