AN154: Determination of Inorganic Anions in Environmental Waters Using a Hydroxide-Selective Column

Instrument Type: IC

In this application, we describe the use of automated eluent generation, combined with a high-capacity, hydroxide-selective, anion-exchange column—the Thermo Scientific Dionex IonPac AS18—for the determination of inorganic anions in environmental waters. The hydroxide-selective Dionex IonPac AS18 column is a superior alternative to the Thermo Scientific Dionex IonPac AS9-HC column using carbonate eluent, which is described in EPA Method 300.1.
