Carboxen® Carbon Adsorbent

Description

• General description: 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: Evaluation of selected solid adsorbents for passive sampling of atmospheric oil and natural gas non-methane hydrocarbons: This study assesses different adsorbents including Carboxen for capturing non-methane hydrocarbons in the air, crucial for environmental monitoring and regulatory compliance (Helmig et al., 2022). Application of Thin-Film Microextraction to Analyze Volatile Metabolites in A549 Cancer Cells: Discusses the application of Carboxen adsorbents in microextraction techniques for analyzing volatile compounds from cancer cells, demonstrating its utility in medical research and diagnostics (Filipiak et al., 2021).
