The IonPac® ATC-3 Anion Trap Column contains a high-capacity, low-efficiency, anion-exchange resin in the hydroxide form. The column strips trace contaminants from hydroxide or borate eluents. The trap is installed in the eluent line prior to the injection valve to prevent spurious peaks during gradient chromatography and to minimize baseline shifts during gradient operation.
