Will Sep-Pak C18 bind polar compounds from water samples? - WKB108777

Article number: 108777

ENVIRONMENT

  • Solid-phase extraction (SPE)
  • Sample preparation
  • Sep-Pak C18
  • Oasis

ANSWER

No

ADDITIONAL INFORMATION

Sep-Pak C18 is not expected to retain polar compounds from water. This is a hydrophobic packing material that does not generally retain polar analytes.

Use of a Sep-Pak product for polar compound retention from water samples would need to be investigated.

The Oasis family of SPE packings may provide retention of some polar analytes from water, especially the mixed-mode sorbents, which target ionizable compounds.
