Copure® Carb-GCB SPE

Copure® 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. Features: Higher extraction speed
