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：
  • 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

更多有关我们的专业碳吸附剂的资料，请见sigma-aldrich.com/carbon
Carbotrap®/Carbopack™吸附剂可承受高烘烤温度而不会损失机械和化学完整性。 它对异戊二烯具有高亲和力并且不会保留大量的水。此外，如果包装得太紧，它会有粉化的倾向。
