 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.
