General description
Carboxen® 1003 was used for the adsorption of lipopolysaccharides (LPS) as it can accommodate large LPS and their agglomerates.
Carboxen® Adsorbent is ideally used for solid-phase microextraction (SPME). It is highly efficient in extraction of small polar molecules from aqueous solution.
Carboxens are a highly engineered synthetic carbon adsorbent engineered from polymeric precursors. These particles will not plastically deform like resins or generate fines like activated carbon. These materials are shipped and stored dried. These derivatized resins bring value to a wide range of purification applications for removing both small and large molecule impurities. They find use in both gas and liquid phase purifications. Some examples include removal of homogenous catalysts from active pharmaceutical ingredients (API)s, high-risk impurities in biochemical purifications such as host cell proteins from mAbs, removal of toxic heavy metals, purification of chlorinated molecules, and removal of extractables and leachables. Tapered pores result in increased thermodynamic and kinetic properties for both adsorption and desorption. The Carboxens vary in the relative percentage of pore structures (micro, meso, and macro), surface area, and surface pH.
