General description
A carbon molecular sieve (CMS) is the porous carbon skeletal framework that remains after pyrolysis of a polymeric precursor. These particles are:
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.

- 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

Doxorubicin has been widely used in the treatment of cancer. However, acquired doxorubicin resistance severely hinders the application of the drug. In the present study, doxorubicin resistance was investigated in lung carcinoma. microRNA-155 (miR-155) was found to be upregulated in

Tetrachloroethene, also known as perchloroethylene (PCE), is a common groundwater contaminant throughout the United States. The incomplete reductive dechlorination of PCE--resulting in accumulations of trichloroethene, dichloroethene isomers, and/or vinyl chloride--has been observed by many investigators in a wide variety of

Toluene is a volatile organic compound, one of 189 hazardous air pollutants (HAPs) and the most important pollutant found in most industries and indoor environments; owing to its adverse health, toluene must be treated before being released into the environment.
