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

Carbotrap®/Carbopack adsorbent can withstand high bake-out temperature without losing the mechanical and chemical integrity. It has a high affinity for isoprene and does not retain significant amounts of water. Furthermore it has a tendency to pulverize if it is packed too tightly.


Carbotrap X has a very high specific surface area and was used for the recovery of low boiling hydrocarbons like 1,3-butadiene and isoprene.
