Answer:This analytical column is 4 mm ID × 250 mm long.
Answer:The column uses 4 µm particles and has a capacity of 240 µeq.
Answer:It is designed for trace oxyhalides and inorganic anions, including low-level bromate in drinking water.
Dionex™ IonPac™ AS19-4 µm is a hydroxide-selective anion-exchange column for high-resolution separation of trace oxyhalides and inorganic anions in drinking-water and environmental samples. This configuration is a 4 × 250 mm analytical column packed with 4 µm polymeric particles and has a capacity of 240 µeq. The stationary phase uses alkanol quaternary ammonium functionality and is optimized for operation around 30 °C. The column supports bromate determination at low µg/L levels and meets or exceeds performance requirements associated with U.S. EPA Methods 300.0 and 300.1. It operates at approximately 1.0–1.5 mL/min and is rated to 5000 psi.
