Carbograph™ packings are graphitized carbon blacks equivalent to the Carbopack packings. There are three different types of graphitized carbon blacks (Carbograph™ 1 and 2). Unlike diatomites that must have a stationary phase, Carbograph™ packings possess partitioning properties without any surface modifications. Carbograph™ packings can also be modified with a stationary phase giving them unique selectivities.
Carbograph™ 1 Equivalent to Carbopack™ B. Obtained by graphitization and granulation. It has a surface area of 100m2/g. Carbograph™ 1-TD has a coarse mesh of 20/40 which is suitable for thermal desorption work. Maximum temperature 500oC.
Carbograph™ 1SC Similar to Carbopack™ BHT. It is a type of Carbograph™ 1 that is manufactured specifically for the separation of sulfur compounds SF6, SO2, H2S, COS, mercaptans, and disulfides. It is also suitable for analysis of sulfurs in oil products. Maximum temperature 225oC.
Carbograph™ 2 Equivalent to Carbopack™ C. It has a specific surface of 10m2/g. It can be used alone as an uncoated adsorbent packing for the separation of volatile organic compounds. Carbograph™ 2- TD has a coarse mesh of 20/40 which is suitable for thermal desorption work. Maximum temperature 500oC.
