The Thermo Scientific 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 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. The IonPac AS24 4 × 250 colum is ideal for the development of specialized applications, providing excellent separation of environmental anions including inorganic anions, oxyhalides, oxyanions, and organic acids.
