DESCRIPTION
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.
