一般說明

Carbotrap®/Carbopack 吸附剂可以承受较高的烘烤温度,同时不会失去其机械和化学完整性。它对异戊二烯具有很高的亲和力,并且不会保留大量的水。此外,如果包装得过紧可能会导致内容物粉碎。
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
