IC Trap Columns

Columns to Purify Eluent or Polish Samples

Trap columns are short columns installed in the system to prevent unwanted analytes from interfering with the separation of your analytes of interest. IonPac® trap columns contain high-capacity, low-efficiency, ion-exchange resin. The columns strip trace contaminants from the eluent and prevent them from reaching the guard and analytical columns. Polisher columns are specialized columns that remove unwanted counterions from the sample, and are installed between the sampler and injector.

Anion IC and RFIC Trap Columns

IonPac Anion Trap Columns contain high-capacity, anion-exchange resin in the hydroxide form. The anion trap column is installed in the eluent line prior to the injection valve to prevent eluent contaminants from causing spurious peaks during gradient chromatography.

Cation IC and RFIC Trap Columns

IonPac Cation Trap Columns contain high-capacity, cation-exchange resin in the hydronium form. The cation trap column is installed in the eluent line prior to the injection valve to prevent eluent contaminants from causing spurious peaks during gradient chromatography.

Cation Polisher Columns for Anion Analysis

IonPac CP Cation Polisher Columns are designed for removal of metallic contaminants and other cations such as calcium and magnesium from the sample stream while performing anion analysis.

Dionex IonPac MFC-1 Metal-Free Trap Columns

The Thermo Scientific Dionex IonPac MFC-1 and MFC 500 metal-free columns contain a special chelating resin. These columns are placed in the eluent line prior to the injection valve to remove transition metals from high-pH eluents.
