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
