Supelclean Sulfoxide SPE

Retention Mechanism: Normal-phase
Sample Matrix Compatibility: Hexane extracts of transformer, waster, and mineral oil

  • Consists of a patent pending silica-bonded sulfoxide (-SO) SPE phase
  • Developed specifically for the extraction of polychlorinated biphenyls (PCBs) from transformer, waster and mineral oil
  • PCB retention is facilitated via interaction between the SPE phase′s electrophilic sulfur atom and the pi-electron cloud formed from aromatic rings inherent with PTBs
  • This unique SPE phase offers a simple and efficient sample prep method for identifying PCBs at quanititation limits of 0.5 ppm
  • When using the polypropylene SPE tube version, a large volume reservoir is recommended for increasing SPE volume headspace
  • The glass SPE version is of unique design and is threaded on the mouth of the SPE tube. This allows for a screw-top cap and female luer plug to reduce moisture contamination during shipment and storage.
