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.
