DESCRIPTION
Concentrate weak cations such as base amines using the mixed-mode, reversed-phase, cation-exchange functionality of the Thermo Scientific™ Dionex™ SolEx™ SCX Polymer-Based SPE Cartridge in extremely acidic sample. The strong cation exchange (SCX) phase bears sulfonate (SO3-) sites which can exchange cations down to a pH <1. The cartridge is designed for use with the Thermo Scientific™ Dionex™ AutoTrace™ 280 SPE system or other SPE instrumentation and vacuum manifolds.
