Thermo Scientific Dionex IonPac AS26 Hydroxide-Selective Anion-Exchange Column

For Separation of Haloacetic Acids and Bromate in Drinking Water Using Two-Dimensional Ion Chromatography (2D-IC) Analysis

The Thermo Scientific Dionex IonPac* AS26 hydroxide-selective anion-exchange column is specifically designed for 2D-IC separation of haloacetic acids (HAAs) in drinking water. The capacity and selectivity of this column enables analysis of haloacetic acids in drinking water at low-μg/L concentrations. The Dionex IonPac AS26 column is available in standard bore (4 × 250 mm), microbore (2 × 250 mm), and capillary (0.4 × 250 mm) formats, supporting flow rates from 10 µL/min to 3 mL/min. 

  • High capacity: 250 μeq per column (4 × 250 mm)
  • Determines HAAs in high-ionic-strength matrices without sample pretreatment
  • Column selectivity optimized for a 15 ºC operating temperature
  • Compatible with HPLC organic solvents
  • Used as second-dimension column in 2D-IC method for HAAs (0.4 × 250 mm)
