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 include:
- Superior selectivity and efficiency in the separation of proteins and biomolecules
- High stability under extreme operating conditions
- High density polyethyleneimine functional groups that provide improved recovery compared to conventional WAX
