          IonPac AS19 Hydroxide-Selective Anion-Exchange ColumnThe IonPac® AS19 hydroxide-selective anion-exchange column is specifically designed for trace bromate in drinking water.

          詳細(xì)介紹

          For Determination of Oxyhalides and Inorganic Anions

          The IonPac® AS19 hydroxide-selective anion-exchange column is specifically designed for trace bromate in drinking water. Its high capacity and selectivity allow the determination of bromate in drinking water at the low-μg/L level. The IonPac AS19 columns meets the performance requirements of US EPA Methods 300.0 and 300.1.

          The new 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.

          • Recommended hydroxide-selective column for trace bromate in drinking water matrices

          • High capacity: 240 μeq per column (4 × 250 mm)

          • Meets or exceeds performance requirements of US EPA Methods 300.0 and 300.1

          • Column selectivity is optimized for 30 °C operating temperature

          • Compatible with organic solvents

          • Low background signal and enhanced analyte sensitivity with the ASRS® 300 and an RFIC system

          The IonPac AS19 is designed for the analysis of oxyhalides and common inorganic anions including fluoride, chlorite, bromate, chloride, nitrite, bromide, chlorate, nitrate, phosphate, and sulfate in drinking water, groundwater, wastewater, and other diverse sample matrices. The IonPac AS19 allows analysis of most drinking water without the use of sample pretreatment or preconcentration. This column is ideally used with an RFIC system for automatic eluent generation.

          The key application for the IonPac AS19 is the determination of trace bromate in drinking water matrices using a potassium hydroxide gradient with suppressed conductivity detection. The selectivity of the AS19 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.

          Note: Use the Anion Self-Regenerating Suppressor (ASRS 300) with the IonPac AS19 column for eluent suppression.
