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
