The determination of common inorganic anions in drinking water is one of the most important applications of ion chromatography (IC) worldwide. Ion chromatography has been approved for compliance monitoring of these common inorganic anions in U.S. drinking water since the mid-1980s, as described in U.S. EPA Method 300.0. This application note describes the determination of inorganic anions in drinking water and other environmental waters using an IonPac AS14 column and conditions that are consistent with those in U.S. EPA Method 300.0.

The determination of common inorganic anions in environmental waters is one of the most important applications of ion chromatography (IC). This Application Note describes the determination of inorganic anions in wastewater and other environmental waters using conditions that are consistent with those in U.S. EPA Method 300.0. In addition to the Thermo Scientific Dionex IonPac AS4A-SC column, the Dionex IonPac AS14 and Dionex IonPac AS9-HC column are also discussed as options for this method. See AN 135 (a), (b), and (c), respectively.

The U.S. National Primary Drinking Water Standards specify a Maximum Contaminant Level (MCL) for a number of inorganic anions to minimize potential health effects. In this Application Note, we describe the use of the IonPac AS14A anion exchange column for the routine high throughput determination of common inorganic anions in drinking water matrices. The IonPac AS14A provides greater speed and efficiency, ruggedness equivalent to the AS4A-SC column, improved separation of fluoride from the void volume (water dip), and better overall separation selectivity.
