These flangeless vac cartridges feature Oasis WCX sorbent, a polymeric reversed-phase, weak ion exchange mixed-mode sorbent. They are optimized for fast, simple, and highly selective sample preparation of strong basic compounds and quaternary amines.
- Sorbent is water wettable, maintaining high retention and excellent recoveries even if dry.
- Eliminates the need for extraordinary steps to prevent sorbent beds from drying out during pre-sample loading.
- Flangeless configuration allows cartridges to be closely packed for processing in specialized automated SPE systems.
