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.
