一般描述
石墨化炭黑（GCB）可以是无孔的或多孔的。石墨化过程产生高纯度表面，具有很好的吸附和解吸（如果需要）性质。表面相互作用仅取决于色散（伦敦）力。这些粒子的特性包括：
通常，相对于碳分子筛（CMS）吸附剂，GCB 吸附剂吸附强度相对较弱，与球形石墨化聚合物碳（SGPC）吸附剂相似。我们的 Carbotrap 产品是一种 GCB 吸附剂。

Carboxen® 569 was used for trapping a range of replacement chlorofluorocarbons varying in boiling point from -48.4 to -9.8°C which is highly advantageous for analysis of trace gases in atmosphere.
Carboxen® Adsorbent is ideally used for solid-phase microextraction (SPME). It is highly efficient in extraction of small polar molecules from aqueous solution.
