IonPac AS24 Hydroxide-Selective Anion-Exchange Column

For Separation of Haloacetic Acids and Bromate in Drinking Water 

The Thermo Scientific Dionex IonPac? AS24 is a high-capacity hydroxide-selective anion-exchange column optimized for the separation of haloacetic acids (HAAs) as well as a variety of environmental anions. The capacity and selectivity enables analysis of haloacetic acids in drinking water at low-μg/L concentrations. The Dionex IonPac AS24 2 × 250 mm column is specifically designed for separation of haloacetic acids in drinking water prior to MS or MS/MS detection and is the specified column in US EPA Method 557. 

  • Specified column for US EPA Method 557 (2 × 250 mm)
  • High capacity: 140 μeq per column (2 × 250 mm)
  • Determine HAAs in high-ionic strength matrices without sample pretreatment
  • Column selectivity is optimized for a 15 oC operating temperature
  • Compatible with HPLC organic solvents
  • Used as second dimension column in 2-D method for bromate in US EPA Method 302.0 (2 × 250 mm)
  • Extended application capabilities providing excellent separation of environmental anions
