IC and BioIC Trap Columns

Remove contaminants and unwanted analytes

Prevent contaminants and unwanted analytes from interfering with analytes of interest by using Thermo Scientific™ IonPac™ trap columns. These short columns contain high-capacity, low-efficiency, ion-exchange resin. Specialized polisher columns, installed between the sampler and injector, remove unwanted counter ions from the sample.

Anion trap columns

Dionex IonPac Anion Analyte Trap ColumnRemoves all analyte anions from a sample in Reagent-Free Ion Chromatography systems with Eluent Regeneration (RFIC-EG)
Dionex ATC Anion Trap ColumnsContains high-capacity, low-efficiency anion-exchange resin that rermoves trace anion contaminants from hydroxide or borate eluents
Dionex CR-TC Continuously Regenerated Anion Trap ColumnsElectrolytically regenerated anion trap columns continuously remove all anionic contaminants from eluent without the need for offline chemical regeneration, and provide very low baseline drift during gradient operations
Dionex IonPac ATC-HC and ATC-HC 500 Anion Trap ColumnsHigh-capacity anion-exchange trap column designed for use with RFIC-EG systems columns, that strip anionic contaminants from deionized water or RFIC-EG eluents to prevent them from reaching the guard or analytical column

Cation trap columns

Dionex IonPac Cation Analyte Trap ColumnContains high-capacity cation-exchange resin in the hydronium form.
Dionex CR-CTC Continuously Regenerated Cation Trap ColumnsHigh-pressure, electrolytically regenerated trap columns that continuously remove cationic contaminants from eluents without the need for off-line chemical regeneration, and provide low drift during gradient operations.
Dionex CTC Cation Trap ColumnsHigh-capacity, low-efficiency cation-exchange trap columns that remove trace cation contaminants from eluents. Installed in the eluent line after the pump prior to the injection valve to prevent spurious peaks and reduce baseline shifts during gradient chromatography.
Dionex IonPac CP Cation Polisher Columns (CP1 Na+, CP2 H+)Cation polisher columns that extend analytical column and suppressor lifetimes by removing and reducing deposition of metallic and other cation contaminants when analyzing anions in matrices that contain high levels of multivalent cations. Well suited for phosphate analysis with metallic contaminants.
Dionex MFC-1 Metal-Free Trap ColumnsColumns packed with special chelating resin that removes trace transition metal contaminants from high-pH eluents.
