MilliporeSigma™ Supelco™ Carbotrap™ Adsorbent, Matrix Carbotrap™ C, 20-40 mesh

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.
