Solid phase extraction disk, ENVI™-18

Solid phase extraction disks provides faster flow rates and exhibits less clogging than PTFE discs for the extraction of organic contaminants from drinking water samples.

• Reversed phase retention mechanism
• Porous glass fiber membranes embedded with C18 or C8 modified silica particles

Applications include polynuclear aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), phthalates, semivolatile organics, paraquat and diquat, pesticides and herbicides.
