Sepax HP-SCX Columns

Description

HP-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 unique 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. The uniform polymeric bonding of HP-SCX enhances its stability under

various separation conditions.HP-SCX has expanded its applications from the traditional SCX

separation of cationic and nitrogen containing compounds to weak cationic and neutral organic

molecules. Examples include separation of analytes of amines and polyamines, such as alkaloids,

peptides, codeine, and cough and cold ingredients.
