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

Reductive dechlorination of high concentrations of tetrachloroethene to ethene by an anaerobic enrichment culture in the absence of methanogenesis.

T D DiStefano et al.

Applied and environmental microbiology, 57(8), 2287-2292 (1991-08-01)

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

Performance catalytic ozonation over the carbosieve in the removal of toluene from waste air stream.

Mohammad Reza Samarghandi et al.

Journal of research in health sciences, 14(3), 227-232 (2014-09-12)

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.

Evaluation of a sampling method for the measurement of occupational exposures to ethylene.

John L Martin et al.

Journal of occupational and environmental hygiene, 1(6), 363-370 (2004-07-09)

In an effort to assess the scope of occupational exposures to ethylene, the Olefins Panel of the American Chemistry Council designed and conducted a research project to develop and apply a sampling and analytical method to measure workplace exposure. The

Development and validation of personal monitoring methods for low levels of acrylonitrile in workplace atmosphere: II. Thermal desorption and field validation.

R A Borders et al.

American Industrial Hygiene Association journal, 47(3), 158-163 (1986-03-01)

Thermal desorption is a more sensitive alternative to solvent desorption for the determination of acrylonitrile in air. A dual-bed collection tube (Tenax GC and Carbosieve B) was developed for collecting and concentrating low levels of acrylonitrile. Two thermal desorption techniques

Cryogenic trapping for determination of odor concentration.
