General description

A carbon molecular sieve (CMS) is the porous carbon skeletal framework that remains after pyrolysis of a polymeric precursor. These particles are:
  • Spherical (better packed bed performance than granular particles)
  • Hard and non-friable (pack well, will not break)
  • Highly porous (high surface areas)
  • Used for molecules with an analyte size relative to C2-C5 n-alkanes
  • Hydrophobic (can be used in high humidity environments)

Generally, CMS adsorbents offer greater relative adsorptive strength compared to spherical graphitized polymer carbon (SGPC) and graphitized carbon black (GCB) adsorbents. Our Carbosieve products are a type of CMS adsorbent.
  • Have non-tapered pores
  • Very strong adsorptive strength due to only containing micropores
  • Provide great performance for many small, volatile analytes that most adsorbents have trouble retaining

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. Is this product a packed column?

    This is packing material only; it is not a column. Some endusers will purchase this bottle of packing and prepare their own packed columns.

  4. How can I purchase a column that is packed with this material?

    Most packed column are custom made and require that you obtain a quotation. Please contact our Customer & Sales Services group at phone number (800)-247-6628, fax number (800)-447-3044 or email CIBelle@sial.com for additional information.

You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  6. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  7. What is the maximum temperature for this packing?

    The maximum temperature for this packing is 200 °C.

  8. What does the 80/100 stand for in the product description?

    The 80/100 refers to the mesh size range of the actual particles.  When working with mesh size: the larger the mesh number, the smaller the diameter of the particle.  In this case 80 refers to a diameter of 177 microns and 100 refers to a diameter of 149 microns.  Therefore; the particles in this product with 80/100 will range between 149 microns and 177 microns.
