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：
  • 颗粒状
  • 易碎
  • 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）吸附剂相似。我们的 Carbotrap 产品是一种 GCB 吸附剂。
  • 颗粒为 20/40 目
  • 这些大颗粒允许高流速，无过多的压降

In-community non-invasive identification of asthma-specific volatile organic compounds (VOCs) in exhaled breath presents opportunities to characterize phenotypes, and monitor disease state and therapies. The feasibility of breath sampling with children and the preliminary identification of childhood asthma markers were studied.
