一般說明

碳分子筛(CMS)是在聚合物前体热解后保留的多孔碳骨架。 这些粒子是:
  • 球形(比粒状颗粒具有更好的填充床性能)
  • 坚硬且不易碎(填充好,不会破裂)
  • 高度多孔的(高表面积)
  • 用于具有相对于C2-C5正烷烃分析物大小的分子
  • 疏水的(可在高湿度环境中使用)

通常,与球形石墨化聚合物碳(SGPC)和石墨化炭黑(GCB)吸附剂相比,CMS吸附剂可提供更大的相对吸附强度。我们的Carbosieve产品就是一类CMS吸附剂。
  • 具有非锥形的孔
  • 由于仅含有微孔而具有非常强的吸附强度
  • 为大多数吸附剂难以保留的小型挥发性分析物提供卓越的性能

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 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.

Journal of environmental monitoring : JEM, 4(3), 361-370 (2002-07-04)
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

文章

Carbon Molecular sieves (CMS) are a versatile range of adsorbents that can be tailored for specific applications. Supelco® scientists have been synthesizing synthetic CMS carbons for several decades, starting from tailoring of the starting polymers/copolymers, to modifying the final properties of the subsequent CMS carbon.
