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：
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。

- 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
