Dionex IonPac AS20 capillary columns are packed with the same materials as standard bore columns (with the same performance as 4 mm columns) but at 1% eluent flow rate. The advantage of capillary tubes is that the amount of eluent used is significantly reduced, thereby reducing operating costs.

• This hydroxide selective anion exchange column is recommended for the analysis of trace perchlorate in environmental water samples
li>
• High capacity: 310µeq per column. (4 x 250mm)
• Increase mass sensitivity, reduce eluent consumption, and reduce operating costs
• Ability to operate at room or elevated temperatures; column selection optimized for 35°C operating temperature
• Compatible with organic solvents

• use this column with Reagent-Free™ Ion Chromatography (RFIC™) system and eluent generator are used together to achieve excellent detection limits.
• Use the Thermo Scientific™ Dionex™ Anionic Electrolysis Regeneration Suppressor (AERS™ 500) or the Thermo Scientific™ Dionex™ Anionic Capillary Electrolysis Suppressor (ACES™ 300) with a Dionex IonPac AS20 column to achieve The eluent inhibits and improves analyte detection sensitivity.
• Pre-concentrate the sample using a Thermo Scientific™ Cryptand C1 Concentration Column to analyze trace levels of perchlorate using an analytical column.
