SMT WCX Bulk Packings are silica-based Weak Cation Exchange packing materials developed for separation of cationic compounds. SMT WCX Bulk Packings consist 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.
SMT Bulk WCX is silica based and the packing material is mechanically stable at high flow rates and high pressures up to 6,000 psi.
SMT WCX bulk packings do not swell with organic solvents, salts, or pH gradients.
Special features of SMT BWCX packing material include:
- Superior selectivity and efficiency in the separation of proteins and biomolecules
- High stability under extreme operating conditions
- High density carboxylic acid functional groups provide much better analyte recovery compared to conventional WCX
We manufacture a variety of silica based bulk packing materials for analytical to large-scale purifications. SMT offers a range of bulk WCX packings resins for those who prefer to pack their own column hardware. Samples from different lots can be purchased for method and process validation.
Silica gel and Bulk Packing materials for process scale applications are available in various particle sizes and pore sizes: 10, 20, 35, 60µm and 60, 100, 150 and 300Å are stock sizes.
