The IonPac™ AS24 is a high capacity hydroxide selective anion exchange column optimised 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 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.

• Determine HAAs in high-ionic strength matrices without sample pretreatment
• Column selectivity is optimised for a 15 °C operating temperature
• Compatible with HPLC organic solvents
• Used as second dimension column in 2-D method for bromate in US EPA Method 302.0
• Extended application capabilities providing excellent separation of environmental anions
