General description
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)吸附剂类似。我们的Carbopack产品是一种GCB吸附剂。

- 颗粒状
- 粉末状
- 用于相对于C3-C20+正构烷烃分析分子大小
- 疏水性（可用于高湿度环境）
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)吸附剂类似。我们的Carbopack产品是一种GCB吸附剂。
- 粒径为40目或更小
- 使用40/60目防止串流（如果使用20/40目碳捕集吸附剂观察® ）
- 用更小的目数（60/80，80/100等）开展其他应用
- 只要应用能够应对压降，即可使用最小可用粒度
