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.
