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).

• All cartridges are manufactured using high density polypropylene and have polyethylene frits unless otherwise noted
• Extract semivolatile organic compounds
• Deep-pore design reduces clogging and allows faster flow rates
• Lower cost than PTFE disks
