MilliporeSigma™ Supelco™ Supelclean™ Sulfoxide SPE Tube, PE Frit, Bed Wt. 3 g
Solid phase extraction (SPE) is a technique commonly used in laboratories to isolate analytes of interest from complex matrices.
Manufacturer: MilliporeSigma™ Supelco™ 55253U
DescriptionSupelclean Sulfoxide SPE consists of a silica-bonded sulfoxide (-SO) phase. The technology was specifically developed for the extraction of polychlorinated biphenyls (PCBs) from transformer, waste 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 PCBs. This unique SPE phase offers a simple and efficient sample prep method for identifying PCBs at quantitation limits of 0.5 ppm.
