Waters Corp Oasis Vac Cartridge, 6 cc, 200 mg Sorbent, 30 μm
The 6 cc Oasis HLB cartridge contains Oasis HLB sorbent, a universal polymeric reversed-phase sorbent that allows for the extraction of a wide range of acidic, basic, and neutral compounds from various matrices using a simple, generic method. The Oasis HLB sorbent is water-wettable, which means it maintains high retention and excellent recovery even if the sorbent bed dries out. This eliminates the need for special measures to prevent the sorbent bed from drying before critical steps such as sample loading.
- Syringe-shaped cartridges for use with vacuum extraction devices and automated SPE instruments.
- Universal polymeric reversed-phase sorbent enables extraction of acidic, basic, and neutral compounds.
- Water-wettable sorbent maintains high retention and recovery, even if dry.
- Eliminates need for special measures to prevent sorbent bed from drying out.
