SMT-SCX columns are silica-based Strong Cation eXchange packing materials developed for separation of cationic compounds. SMT-SCX consists of chemically attached hydrophilic surface derivatized to form sulfonic acid functionality. The technique of SAM is used in the bonding process to significantly increase the functional ligand density.
Special features include:
- Superior selectivity and efficiency in the separation of proteins and biomolecules with medium to high [isoelectric point] or pH values
- High stability under extreme operating conditions
- High density sulfonic acid functional groups that provide improved recovery compared to conventional SCX
