Copure® Carb-GCB Graphitized Carbon Black

Copure^® Carb-GCB (Graphitized Carbon Black) is composed of non-porous, flake-like molecules with aromatic hexagonal ring structures. It has a positive charge and dual retention mechanisms of reverse-phase and ion exchange, capable of retaining both non-polar compounds (such as organochlorine pesticides) and highly polar compounds (such as surfactants). Carb-GCB, being a non-porous material, allows for very fast extraction speeds and has a higher adsorption capacity than silica gel.
