Supel-Select SPE

Supelco′s Supel-Select SPE are hydrophilic modified styrene based polymers developed for the solid phase extraction of a broad range of compounds from aqueous samples. The retention mechanism for HLB is predominantly based on reversed-phase interaction. However, because the phase is hydrophilic modified, it is also selective for more polar compounds. The retention mechanism for SCX/SAX is predominantly based on ion exchange.

Features & Benefits
  • Excellent sample prep performance at a lower price
  • Amenable to generic methodology - save time, money, and effort during method development
  • Greater capacity allows for smaller bed weights = smaller elution volumes = time savings in sample processing
  • Resistance to overdrying allows for more robust methodology
  • Low UV and MS extractables for lower background and greater sensitivity
  • Stringent Production & QC guidelines offer greater lot-to-lot, tube-to-tube, and well-to-well consistency for improved accuracy and precision
