Carbon Molecular Sieve



These materials are primarily used for collecting very small molecular-sized compounds (C2-C5). The size and shape of the analyte molecule and the size and shape of the pores in the CMS particle determine how well the analyte is adsorbed and desorbed.
Our Carbosieve™ S-III and Carboxen™ carbon molecular sieves have upper temperature limits of at least 400°C.

  • Carbosieve™-SIII has large surface area (975m2/g) and 15-40Å pores, making this spherical carbon molecular sieve excellent for trapping small airborne molecules
  • Carbosieve™-SII is recommended for analyzing mixtures of permanent gases (H2, O2, Ar, CO and CO2) and C1-C2 hydrocarbons (methane, ethane, ethylene, acetylene).
  • Carbosieve™-G is recommended for analyzing C1-C3 hydrocarbons. Maximum Temperature <200°C with oxygen free carrier gas.
