Dionex™ ATC Anion Trap Columns Thermo Scientific™

Remove trace anion contaminants from hydroxide or borate eluents with the Thermo Scientific™ Dionex™ IonPac™ ATC-3 and Dionex IonPac ATC 500 Anion Trap Columns. These trap columns are installed in the eluent line after the pump prior to the injection valve to prevent spurious peaks and to minimize base line shifts during gradient operation. The Dionex IonPac ATC 500 is identical to the Dionex IonPac ATC-3, but is packed in a column body that is compatible with the nonstop operation of high-pressure ion chromatography Thermo Scientific™ Dionex™ HPIC™ system pressures up to 5000 psi (34.5 MPa).

Dionex™ IonPac™ ATC-HC and ATC-HC 500 Anion Trap Columns Thermo Scientific™

Use Thermo Scientific™ Dionex™ IonPac™ ATC-HC and ATC-HC 500 Anion Trap Columns to strip anionic contaminants from deionized water or RFIC-EG eluents to prevent them from reaching the guard or analytical column. These high-capacity trap columns are designed specifically for use with RFIC-EG systems. The Dionex IonPac ATC-HC 500 column is identical to the Dionex IonPac ATC-HC column but packed in a column body that is compatible with non-stop operation at HPIC system pressures up to 5000 psi (34.5 MPa).

Dionex™ CR-TC Continuously Regenerated Trap Columns Thermo Scientific™

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.

Dionex™ Trap Column/Suppressor Cleanup Kit Thermo Scientific™

Use the Thermo Scientific™ Dionex™ Trap Column/Suppressor Cleanup Kit to deliver reagent solutions to regenerate and cleanup our trap columns and suppressors. This stand-alone pneumatically driven reagent delivery system eliminates the need for using the analytical pump for delivery of concentrated acids, bases or other reagents that can contaminate the IC system. The kit consists of a 1L plastic reservoir, a gas pressure regulator, a two-way liquid shut-off valve, and tubing and connection fittings. The kit is pre-assembled and easy to install and operate.

Dionex™ IonPac™ Anion Analyte Trap Column Thermo Scientific™

The Thermo Scientific™ Dionex IonPac Anion Analyte Trap Column will remove all the analyte anions from a sample in RFIC systems with Eluent Regeneration.
