Graphitized Carbon Black (GCB) Adsorbents

A graphitized carbon black (GCB) can be non-porous or porous. The graphitization process results in a highly pure surface with great adsorption and desorption (if required) properties. Surface interactions depend solely on dispersion (London) forces. These particles are:
  • Granular
  • Friable
  • Used for molecules with an analyte size relative to C3-C20+ n-alkanes
  • Hydrophobic (can be used in high humidity environments)

Generally, GCB adsorbents offer weaker relative adsorptive strength compared to carbon molecular sieve (CMS) adsorbents, and similar relative adsorptive strength compared to spherical graphitized polymer carbon (SGPC) adsorbents. We offer three product lines:
  • Carbotrap® Adsorbents - particles are 20/40 mesh
  • Carbopack Adsorbents - particles are smaller than 40 mesh
  • Small Particle GCB Adsorbents - suitable for use in electrochemical and bioprocessing applications
