Oasis WCX 96-well µElution Plate, 2 mg Sorbent per Well, 30 µm Particle Size, 1/pk

The Waters Oasis WCX SPE cartridge is based on a polymeric HLB backbone and has a weak cation-exchange function. The Waters Oasis WCX is used in mixed-mode SPE. The WCX chemistry allows pH-controlled binding and elution of basic compounds with additional RP retention. The application spectrum of the Waters Oasis WCX includes basic analytes, selective extraction from biofluids, peptides and methods with milder elution conditions.

Features and Benefits

• Water-wettable polymer sorbents
• Stable performance over a very wide pH range
• No retention losses due to drying out
• RP and mixed-mode ion exchange
• Cartridge, plate, and µElution formats

Additional Information

Oasis sorbents are based on a macroporous copolymer of N-vinylpyrrolidone and divinylbenzene. This backbone is water-wettable and stable when exposed to strongly acidic and alkaline samples. Oasis HLB utilizes hydrophilic and lipophilic retention components; MCX, MAX, WCX, and WAX combine this polymer base with strong or weak cation- or anion-exchange groups. PRiME HLB is designed for simplified workflows and reduced matrix interference. The selection depends on the charge state, polarity, matrix, and desired elution profile.
