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 ?L/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 ?C operating temperature
- Compatible with HPLC organic solvents
- Used as second-dimension column in 2D-IC method for HAAs (0.4 × 250 mm)
