Answer:The analytical column is 4 mm ID × 150 mm long.
Answer:The column uses 4 µm particles and has a capacity of 126 µeq.
Answer:The AS22-Fast-4 µm phase is designed for carbonate/bicarbonate anion-exchange methods.
Dionex™ IonPac™ AS22-Fast-4 µm is a standard-bore anion-exchange analytical column for rapid determination of common inorganic anions using carbonate/bicarbonate eluents. This configuration is 4 × 150 mm, uses 4 µm polymeric particles, and has a capacity of 126 µeq. The super-macroporous stationary phase carries alkanol quaternary ammonium ion-exchange groups and supports a flow rate of approximately 2.0 mL/min. The column is rated to 5000 psi and is compatible with pH 0–14 and up to 100% HPLC-compatible solvents. It supports methods such as U.S. EPA Method 300.0(A) for routine anion analysis.
