IonPac CTC Cation Trap Column

The IonPac^® CTC Cation Trap Column contains high-capacity, low-efficiency, cation-exchange resin in the hydronium ion form. The column strips trace contaminants from the eluent. The trap is installed in the eluent line prior to the injection valve to prevent spurious peaks and reduce baseline shifts during gradient chromatography.
