Waters Corp Oasis MCX Cartridge, 1 cc/30 mg, Gilson Adapter, 30 μm
The Oasis MCX (Mixed-Mode Cation eXchange) Sorbent is a water-wettable polymeric sorbent stable from pH 0–14. It is designed for selective retention of basic drugs using cation-exchange groups. This mixed-mode solid-phase extraction sorbent provides dual retention, leading to high specificity, increased sensitivity, and cleaner extracts by reducing matrix effects. Effective for enriching analytes, it's recommended for weak bases with a pKa between 2 and 10.
- Tightly controlled ion-exchange capacity of 1 meq/g.
- No silanol groups complicate retention or method development.
- Provides orthogonality and selectivity.
- Offers two screening protocols.
- Captures and concentrates basic compounds while removing matrix interferences.
- Uses 3-step or 4-step methods; 3-step for cleaner results, 4-step for additional matrix removal.

Waters Corp Sep-Pak Alumina A 1 cc Vac Cartridge, 100 mg Sorbent per Cartridge, 50 - 300 µm, 100/pk
Sep-Pak Alumina A Vac cartridges contain a highly active grade of alumina with an acidic surface chemistry. The aluminum oxide surface provides an extremely polar surface for analyte retention and has properties of a Lewis acid. This normal phase sorbent is similar in use to silica; however, it is slightly more stable than unfunctionalized silica under high pH conditions. This acidic alumina is also low-capacity ion exchanger in aqueous media. Unlike polymer-based ion exhangers, this sorbent is unaffected by high-energy radioactivity and can be used for radioactive compound isolation. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
