Dionex™ IonPac™ AS20 IC Columns

The Dionex IonPac AS20 Capillary column is packed with the same material as the equivalent standard bore version (providing the same performance as a 4mm column) but requires only 1% of the eluent flow rate. The capillary format provides the advantage of significantly reduced eluent consumption, which helps reduce operating costs.

• Recommended hydroxide-selective, anion-exchange column for trace perchlorate in environmental water samples
• High Capacity: 310μeq per column. (4 x 250mm)
• Increased mass sensitivity, reduced eluent consumption, and reduced operating costs
• Operates at ambient or elevated temperature; column selectivity is optimized for 35°C operating temperature
• Compatible with organic solvents

• Use this column with a Reagent-Free™ IC (RFIC™) system and an eluent generator for optimum detection limits.
• Use the Thermo Scientific™ Dionex™ Anion Electrolytically Regenerated Suppressor (AERS™ 500) or the Thermo Scientific™ Dionex™ Anion Capillary Electrolytic Suppressor (ACES™ 300) with the Dionex IonPac AS20 column for eluent suppression and enhanced analyte sensitivity.
• Use the Thermo Scientific™ Cryptand C1 Concentrator column for sample preconcentration for analysis of trace perchlorate with the analytical column.
