SMT WCX columns are silica-based Weak Cation Exchange packing materials developed for separation of cationic compounds. SMT WCX consists of chemically attached hydrophilic surface derivatized to form carboxylic acid functionality. The technique of SAM is used in the bonding process to significantly increase the functional ligand density.
Special features of SMT WCX columns include:

SMT SAM WCX – Ion-Exchange WCX Column
WCX columns for separation of proteins, their variants and other cationic compounds. SMT WCX consists of a chemically attached hydrophilic surface derivatized to form carboxylic acid functionality.
SMT SAM WCX – Guard Column
WCX Guard columns are expendable small columns designed to remove anything that may interfere with the separation or shorten the lifetime of the primary column.
