General description
Carbotrap® C was used for the sampling and quantitative analysis of microbially produced volatiles using thermal desorption-gas chromatography.
Carbotrap®/Carbopack™ Adsorbent can withstand high bake-out temperature without losing the mechanical and chemical integrity. It has a high affinity for isoprene and does not retain significant amounts of water. Furthermore it has a tendency to pulverize if it is packed too tightly.
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。
