General description
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.
Application
Carboxen® 569 was used for trapping a range of replacement chlorofluorocarbons varying in boiling point from -48.4 to -9.8°C which is highly advantageous for analysis of trace gases in atmosphere.

The headspace solid-phase microextraction (HS-SPME) efficiencies from vegetable oil of the recently available Carboxen-poly(dimethylsiloxane) (PDMS) and divinylbenzene-Carboxen-PDMS fibres were found to be much greater than those of the PDMS fibre for a number of volatile contaminants. Using these Carboxen-based fibres
