The VOCx and CleanPeakX are highly pure carbon adsorbents for gas and liquid chromatography needs. These adsorbents are available as carbon molecular sieve and graphitized carbon black, and are offered in a variety of pore sizes (6 to 300 Å), surface area (5 to 2,000 m2/g), and particle sizes (20/40, 40/60, 60/80, and 120/400 mesh). VOCX, a family of hydrophobic carbon for gas chromatography and thermal desorption, enhances monitoring of volatile and semivolatile organic compounds in bioanalytical applications. CleanPeakX facilitates selective extraction of polar compounds from biological materials, and can be used in solid-phase extraction tubes and HPLC columns. Custom engineered adsorbents are also offered for specific applications in bioseparation and purification of drugs, antibodies, recombinant proteins, and any preferred biologics.
