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:
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。

Carbopack™ Y was used for determination of contamination caused by pesticides like alachlor, atrazine, captan, formothion, lindane and phosalone in atmospheric samples.[1] Carbopack™ Y was modified with mono-molecular layer of heptakis-(2,3,6-tri-O-methyl)-ß-cyclodextrin and was used in gas chromatography to study the effect of size and spatial structure of adsorbate molecules on adsorption of organic vapours.[2]
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.[3] Carbotrap®/Carbopack™ adsorbent was used to quantitatively determine trace amounts of volatile organic compounds (VOCs) in air.[4] It was also used for designing sampling protocols on the basis of its retention volume of the gaseous organic compounds of interest.[5]
