| 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 For more information about any of our specialty carbon adsorbents, please visit sigma-aldrich.com/carbon |
