CARBOTRAP C 20/40 MESH 10GM

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 Carbotrap products are a type of GCB adsorbent.

• Particles are 20/40 mesh
• These large particles allow high flow rates without excessive pressure drops
