Packed with a special chelating resin, the Thermo Scientific™ Dionex™ MFC-1 and MFC 500 Metal-Free Trap Columns are used in the eluent line prior to the injection valve to remove transition metals from high-pH eluents. The Dionex IonPac MFC 500 is identical to the Dionex IonPac MFC-1, but is packed in a column body that is compatible with nonstop operation up to 5,000 psi.
Remove trace cation contaminants from eluents using the Thermo Scientific™ Dionex™ IonPac™ CTC-1 and Dionex IonPac CTC 500 Cation Trap Columns. These high-capacity, low-efficiency, cation-exchange trap columns are installed in the eluent line after the pump prior to the injection valve to prevent spurious peaks and reduce baseline shifts during gradient chromatography. The Dionex IonPac CTC 500 is identical to the Dionex IonPac CTC-1, but is packed in a column body that is compatible with nonstop operation of high-pressure Thermo Scientific™ Dionex™ HPIC™ system pressures up to 5000 psi (34.5 MPa). For Reagent-Free™ ion chromatography (RFIC™) MSA eluent generation applications, use the Dionex CR-CTC.
Use Thermo Scientific™ Dionex™ IonPac™ CP Cation Polisher Columns (CP1 Na+, CP2 H+) when analyzing anions in matrices that contain high levels of multivalent cations to reduce deposition of contaminants. Metals and other cations can precipitate on guard and analytical columns or suppressors, which can lead to performance issues such as poor peak shapes or poor recoveries for some anions. Well suited for phosphate analysis with metallic contaminants, these columns extend column and suppressor lifetimes.
Remove ionic contaminants from eluents continuously, without the need for offline chemical regeneration. Thermo Scientific™ Dionex™ CR-TC Continuously Regenerated Trap Columns are electrolytically regenerated trap columns specifically designed for Reagent-Free™ ion chromatography (RFIC™) systems. When plumbed after the Thermo Scientific™ Dionex™ EGC Eluent Generation Cartridge, the Dionex CR-TC trap column removes all ionic contaminants from the deionized feed water, providing low drift during gradient operations.
The Thermo Scientific™ Dionex IonPac Cation Analyte Trap Column contains high-capacity, cation-exchange resin in the hydronium form.
