These cartridges are made of glass fiber disks embedded with C18 or C8 bonded silica. These hydrophobic (nonpolar) silica-based adsorbents are ideal to extract hydrophobic analytes from polar matrices, such as water (e.g., pesticides from water).

Supplier: Restek

Highly base-deactivated spherical silica manufactured by Restek. Monomeric C8 bonding. Similar to Pinnacle® DB C18, but the shorter alkyl chain provides less hydrophobic retention. Less retention can be useful for shortening analysis time, if resolution is adequate. Replaces Hypersil® BDS C8 and Pinnacle® C8 Amine.
