Safety Data Sheet:



cmSORB Carbon Molecular Sieve is a porous carbon structure and nonpolar adsorbent. It is a derivation of activated carbon and zeolites combined into a single pellet. Used to adsorb oxygen molecules, carbon molecular sieve (CMS) helps generate nitrogen-rich air at normal temperatures. Carbon molecular sieve is most commonly used in applications where nitrogen-rich air is essential. The pressure swing adsorption (PSA) process requires CMS in the adsorption towers. The PSA system utilizes pressurization and depressurization cycles to direct raw gas between the adsorption towers, producing the highly concentrated nitrogen gas used in the applications below.

  • PSA nitrogen generation
  • Petroleum chemicals
  • Heat treatment of metal
  • Electronic manufacturing
  • Food preservation
  • Plastic and fiber processing
  • All applications where nitrogen is required

Additional information


Store cmSORB HP carbon molecular sieve in a dry location to prevent premature water adsorption. Do not store super sacks outside; ultraviolet radiation and other adverse conditions will negatively impact its integrity and may eventually cause the bag to fail. Reseal packages after opening to prevent contamination and unintended water adsorption. We recommend that you rotate stock so the oldest material is used first.
