Dionex IonPac AS9-HC 阴离子交换柱

High-Capacity Column for the Analysis of Inorganic Anions and Oxyhalides Including Bromate

Specifically designed for trace bromate in drinking water, the Thermo Scientific^? Dionex^? IonPac^? AS9-HC column is the specified column for U.S EPA Methods 300.1 and 317.0.

• For the analysis of oxyhalides and inorganic anions in complex sample matrices

• Simple, isocratic method for trace bromate (5 μg/L) in ozonated drinking water matrices

• Ideal for difficult applications, such as trace nitrite in complex sample matrices

• Improved separation of bromate/chloride, chloride/nitrite, chlorate/nitrate analyte pairs

The Dionex IonPac AS9-HC column is a high-capacity carbonate eluent anion-exchange column with selectivity similar to the Dionex IonPac AS9-SC column. The Dionex IonPac AS9-HC column also supports the analysis of oxyhalides and inorganic anions, including fluoride, chlorite, bromate, chloride, nitrite, bromide, chlorate, nitrate, phosphate, and sulfate. The Dionex IonPac AS9-HC column is specified in validated methods such as U.S. EPA Method 300.1 and 317.0 and meets or exceeds the performance requirements of these methods.

This column separates trace bromate in drinking water matrices using an isocratic carbonate eluent and a large-loop injection. The Dionex IonPac AS9-HC column also offers good retention of fluoride out of the water dip. The column’s high capacity (190 μeq for 4 × 250 mm column) increases retention time to approximately 22 min. Use the Thermo Scientific Dionex Anion Electrolytically Regenerating Suppressor (AERS 500) with the Dionex IonPac AS9-HC column.

The Dionex IonPac AS9-HC column is offered in three formats: standard bore (4 × 250 mm), microbore (2 × 250 mm), and capillary (0.4 × 250 mm). The capillary format is packed with the same material as the equivalent standard bore version (providing the same performance as a 4 mm column), but requires only 1/100th the eluent flow rate. The capillary format provides the advantage of significantly reduced eluent consumption with helps reduce the operating costs.

Note: The Thermo Scientific Dionex IonPac AS23 column is the newest carbonate eluent column recommended for the analysis of oxyhalides including bromate.
