General description

Retention Mechanism: Reversed-phase
Sample Matrix Compatibility: Aqueous solutions (drinking water)

  • The SPE membrane equivalents of ENVI-18 and ENVI-8 packed bed SPE sorbents
  • Porous glass fiber membranes embedded with C18 or C8 modified silica particles.
  • Provides faster flow rates and exhibits less clogging than PTFE discs for the extraction of organic contaminants from drinking water samples
  • Typical applications include polynuclear aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), phthalates, semivolatile organics, paraquat and diquat, pesticides and herbicides
