Recommended use

Target application

Dionex IonPac AS23-4µm IC columns High-capacity column for analysis of inorganic anions and oxyhalides. Improved efficiencies and resolution compared to the Dionex IonPac AS23 column. Requires high-pressure IC. Trace bromate in drinking water. Meets or exceeds performance requirements of EPA 300.0 and 300.1, ASTM 4327, ISO 10304, and ISO 15061.
Dionex IonPac AS23 IC Columns For inorganic anions and oxyhalides, and replaces the Dionex IonPac AS9-HC column. Capillary format reduces eluent consumption and lowers operating costs. Trace bromate in drinking water. Meets or exceeds EPA 300.0 and 300.1.
Dionex IonPac AS22-Fast-4µm IC Columns For fast, high resolution separation of inorganic anions. Requires high-pressure IC for fastest runs. Fast analysis of inorganic anions in drinking water. Meets or exceeds EPA 300.0 and 300.1.
Dionex IonPac AS22 Fast IC Columns For fast analysis of common inorganic anions. Fast analysis of inorganic anions in drinking water. Meets or exceeds EPA 300.0 and 300.1.
Dionex IonPac AS22 IC Columns For fast analysis of common inorganic anions. Provides a newer alternative to Dionex IonPac AS4A-SC, AS12A, AS14 and AS14A columns.   Analysis of common inorganic anions in drinking water, wastewater and process waters. Meets or exceeds EPA 300.0 and 300.1.
Dionex IonPac AS14A IC Columns For analysis of common inorganic anions. The Dionex IonPac AS22, AS22-Fast-4μm and AS22-Fast columns are newer alternatives to this column. Meets or exceeds EPA 300.0 (A). Available in 5μm (3 × 150mm) for fast analysis of common anions.
Dionex IonPac AS14 IC Columns Moderate capacity columns for fast analysis of common inorganic anions with excellent fluoride retention. The Dionex IonPac AS22, AS22-Fast-4μm, AS22-Fast columns are newer alternatives to this column.   Meets or exceeds EPA 300.0 (A) and (B).
Dionex IonPac AS12A IC Columns Moderate capacity columns for inorganic anions and oxyhalides. The Dionex IonPac AS23 column is a newer alternative to this column. Trace chloride and sulfate in high carbonate matrices.
Dionex IonPac AS9-HC IC Columns For inorganic anions and oxyhalides. The high-capacity Dionex IonPac AS23 column is a newer, ideal alternative to this column.
Trace bromate in drinking water. Specified in EPA 300.1 and 317.0.
Dionex IonPac AS4A-SC IC Columns Low capacity columns for fast analysis of common inorganic anions. The Dionex IonPac AS22, AS22-Fast-4μm and AS22-Fast columns are newer alternatives to this column.
Specified in U.S. EPA Method 300.0 (A).
