Extracting herbicides in drinking water


Carb-GCB is composed of sheet-like, nonporous graphitized carbon black with aromatic six-member ring structure and positive charges. It has reversed phase and ion exchange retention mechanisms, retaining non-polar compounds, such as organochlorine pesticides, as well as polar compounds, such as surfactants.Owing to its sheet-like, nonporous structure, Carb-GCB enables higher extraction speed and capability than silica-based sorbents.



  • Higher extraction speed and capability
  • Suitable for large volume samples



Surface area: 100-250 m 2/g
Particle size: 100-300 mesh



  • Removal of pigments in vegetables and fruits.
  • Determination of organochlorine pesticides, ethyl carbamate, alkaloids and mycotoxins in water, beverages, vegetables and seafood
