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

SMT SAM WAX – Ion-Exchange WAX Column
WAX columns for extraction of strong acids from aqueous solvents. These columns consist of chemically attached hydrophilic surface derivatized to form polyethyleneimine functionality.
SMT SAM WAX – Guard Column
WAX Guard columns are expendable small columns designed to remove anything that may interfere with the separation or shorten the lifetime of the primary column.
