High-Capacity Column for the Analysis of Inorganic Anions and Oxyhalides Including Bromate Specifically designed for trace bromate in drinking water, the IonPac® AS9-HC 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 IonPac AS9-HC is a high-capacity carbonate eluent anion-exchange column with selectivity similar to the IonPacAS9-SC column. The IonPac AS9-HC also supports the analysis of oxyhalides and inorganic anions, including fluoride, chlorite, bromate, chloride, nitrite, bromide, chlorate, nitrate, phosphate, and sulfate. The IonPac AS9-HC is specified in validated methods such as US 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 IonPac AS9-HC also offers good retention of fluoride out of the water dip. The column’s high capacity (190 μeq for 4 × 250 mm) increases retention time to approximay 22 min. Use the Anion Self-Regenerating Suppressor (ASRS® 300) with the IonPac AS9-HC column.
