General description

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. Our Carbopack products are a type of GCB adsorbent.
  • Particles are 40 mesh and smaller
  • Use 40/60 mesh to prevent channeling (if observed with a 20/40 mesh Carbotrap® adsorbent)
  • Use smaller mesh (60/80, 80/100, etc.) for all other applications
  • Use the smallest particle size available as long as the application can handle the pressure drop

Articles

Carbon Molecular sieves (CMS) are a versatile range of adsorbents that can be tailored for specific applications. Supelco® scientists have been synthesizing synthetic CMS carbons for several decades, starting from tailoring of the starting polymers/copolymers, to modifying the final properties of the subsequent CMS carbon.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
