일반 설명
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

Air sampling, using sorbents, thermal desorption and gas chromatography, is a versatile method for identifying and quantifying trace levels of volatile organic compounds (VOCs). Thermal desorption can provide high sensitivity, appropropriate choices of sorbents and method parameters can accommodate a

A simple method using active trapping on adsorbents and thermal desorption followed by GC-MS analysis was developed for the indoor air monitoring of monoterpenes. The study was carried out using a dynamically generated atmosphere consisting of 11 monoterpenes: camphene, camphor

A gas chromatographic procedure for the simultaneous analysis of (14)C-labeled and unlabeled metabolic gases from microbial methanogenic systems is described. H(2), CH(4), and CO(2) were separated within 2.5 min on a Carbosieve B column and were detected by thermal conductivity.

While air sampling techniques using adsorbent-based collection, thermal desorption and chromatographic analysis have found a niche in ambient air sampling, occupational applications have been more limited. This paper evaluates the use of thermal desorption techniques for low flow active and
