Measure trace bromate and other oxyhalides in drinking water, ground water, wastewater, and other diverse sample matrices with Thermo Scientific™ Dionex™ IonPac™ AS19 Capillary, Analytical & Guard Columns. The column is specifically designed and recommended for determination of trace bromate, a toxic byproduct of ozone disinfection. The column's high capacity and selectivity facilitate the determination of bromate in drinking water at the low-μg/L level. The Dionex IonPac AS19 columns meet the performance requirements of U.S. EPA Methods 300.0 and 300.1.
The Dionex IonPac AS19 Capillary column is packed with the same material as the equivalent standard bore version (providing the same performance as a 4 mm column), but requires only 1/100th the eluent flow rate. The capillary format provides the advantage of significantly reduced eluent consumption, which helps reduce operating costs.
The key application for this column is the determination of trace bromate in drinking water matrices using a potassium hydroxide gradient with suppressed conductivity detection. The column's selectivity ensures that bromate can be quantified at low μg/L concentrations using suppressed conductivity detection even in the presence of very high concentrations of chloride, sulfate, and carbonate.
