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