Answer:The column is 4 mm internal diameter × 250 mm long.
Answer:The column is designed for isocratic carbonate/bicarbonate eluent.
Answer:It is used for common inorganic anions in drinking water, groundwater, wastewater, process streams and related compliance-monitoring samples.
Dionex™ IonPac™ AS22 is a high-capacity anion-exchange column for fast isocratic analysis of common inorganic anions. This 4 × 250 mm standard-bore configuration is the analytical column and is designed for carbonate/bicarbonate eluents. It supports routine compliance and process monitoring in drinking water, groundwater, wastewater, process streams and scrubber solutions, including workflows aligned with U.S. EPA Method 300.0(A). The 250 mm bed provides the resolving power needed for common anion separations while retaining a straightforward isocratic method format. Use of the corresponding AS22 guard column helps protect the analytical column from sample contamination and extends column service life in routine testing. The standard-bore format is convenient for established laboratory IC systems and provides a robust option for laboratories processing varied aqueous matrices. Consistent carbonate/bicarbonate preparation, suppression and calibration help maintain retention-time stability when the column is used for routine compliance testing.
