Answer:This configuration is 4 mm ID × 30 mm long.
Answer:It is designed for use with the Dionex IonPac AS22-Fast-4 µm analytical column.
Answer:It supports carbonate/bicarbonate anion-exchange methods for common inorganic anions.
Dionex™ IonPac™ AG22-Fast-4 µm is the standard-bore guard column used ahead of the AS22-Fast-4 µm analytical column. This configuration is 4 × 30 mm and is designed for rapid carbonate/bicarbonate anion-exchange methods. The matching phase protects the analytical column from strongly retained matrix components while maintaining the intended selectivity for common inorganic anions. The guard column operates at approximately 2.0 mL/min, is rated to 5000 psi, and supports pH 0–14 with broad compatibility for HPLC solvents. It is suitable for routine environmental and water-analysis workflows, including systems configured for U.S. EPA Method 300.0(A).
