Dionex™ SolEx™ WAX Polymer-Based SPE Cartridge

Concentrate strong anions such as sulfonates using the mixed-mode, reversed-phase, anion-exchange functionality of the Thermo Scientific™ Dionex™ SolEx™ WAX Polymer-Based SPE Cartridge. The WAX stationary phase is comprised of a medium-surface-area divinylbenzene resin particle grafted with an amine functionality. Strong acids are retained at low pH and can be eluted by raising the pH and neutralizing the stationary phase. The cartridge is designed for use with the Thermo Scientific™ Dionex™ AutoTrace™ 280 SPE system or other SPE instrumentation and vacuum manifolds.

About Dionex SolEx SPE Cartridges

Dionex SolEx SPE Cartridges extract organic pollutants from a liquid sample off-line using a solid-phase adsorbent. The cartridges employ a variety of chemistries depending on the application. The silica- or carbon-based absorbents are bound or encapsulated in a membrane filter (called disk format), or packed in a cartridge (syringe bodies). Water (ground, waste, and drinking) is the most common liquid sample extracted, but these SPE cartridges are also used to extract contaminants from milk, fruit juices, urine, and other matrices. These cartridges are desgined for use with Dionex AutoTrace 280 SPE system or other SPE instrumentation and vacuum manifolds.
