Industrial Chromatography

Concentrate strong cations such as quaternary ammonium compounds using Thermo Scientific™  Dionex™ SolEx™ WCX Polymer-Based SPE Cartridge. The WCX stationary phase is comprised of a medium-surface-area divinylbenzene resin particle grafted with carboxylate functional groups. The phase is conditioned at pH 8 or higher, targets can be eluted by protonating the stationary phase to carboxylic acid (neutral), thus eliminating the ion-exchange retention mechanism. 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.
