Description

Length (Metric): 250 mm
Diameter (Metric): 4 mm
Column Type: Analytical Column
Unit Size: Each 1
Analysis of Inorganic Anions and Oxyhalides in Environmental Matrices
• Compliance monitoring of common anions and oxyhalides in drinking water as specified in U.S. EPA Methods 300.1 and 317.0
• Simple, isocratic separation of trace bromate (5μg/L) in ozonated drinking water matrices
• Superior results in difficult applications, such as trace nitrite in complex sample matrices
• Similar selectivity to the Dionex IonPac AS9-SC column, but with higher capacity for improved separation of trace bromate in drinking water
• Solvent compatibility for easy column cleanup after the analysis of samples with hydrophobic componentsMultiple Formats Available for Application Flexibility
• 4 x 250 mm, 2 x 250 mm analytical columns
• 4 x 50 mm, 2 x 50 mm guard columns
• Longer 250 mm columns facilitate higher resolution separations of more complex sample matrices
• Smaller i.d. columns provide higher mass sensitivity, eluent and reagent conservation and lower operating costs

Application Note

Dionex™ IonPac™ AS9-HC is a medium-capacity carbonate-eluent anion-exchange column designed for inorganic anions and oxyhalides in environmental samples. This configuration is a 4 × 250 mm analytical column with approximately 9 µm particles and a stated column capacity of 190 µeq. It is specifically used for trace bromate analysis in drinking water and is associated with U.S. EPA Methods 300.1 and 317.0. The column can resolve bromate, nitrite, and common inorganic anions using isocratic carbonate/bicarbonate eluents and supports complex drinking-water matrices. The stationary phase is based on ethylvinylbenzene/divinylbenzene with quaternary ammonium functionality. The column is rated to 4000 psi and supports approximately 1.0–3.0 mL/min flow.
