Higher Resolution of Trace Oxyhalides and Inorganic Anions in Complex Matrices using Smaller Particle Columns

排列5走势图Achieve high resolution separations of trace oxyhalides and inorganic anions in drinking water using the Dionex IonPac AS19-4μm hydroxide-selective anion-exchange column. Its high resolution, high capacity and selectivity allow the determination of bromate in drinking water at the low-μg/L level. Compared to the previous Dionex IonPac AS19 column, the new anion-exchange column uses smaller resin particles for more efficient separations resulting in more accurate peak integration and more reliable results. It has similar selectivity and increased peak efficiencies compared to the Dionex IonPac AS19 column, ensuring that applications run on the Dionex IonPac AS19 can be easily transferred to the Dionex IonPac AS19-4μm column. The Dionex IonPac AS19-4μm columns meets the performance requirements of US EPA Methods 300.0 and 300.1.

The Dionex IonPac AS19-4μm column is available in three formats: 4 × 250 mm, 2 × 250 mm and 0.4 × 250 mm.The Dionex IonPac AS19-4μm 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

  • High-pressure Thermo Scientific Dionex ICS-5000+排列5走势图 or Dionex ICS-4000 HPIC system is required to run at standard flow rates.

The Dionex IonPac AS19-4μm column 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 Dionex IonPac AS19-4μm column 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 Dionex IonPac AS19-4μm column is the determination of trace bromate in drinking water matrices using a potassium hydroxide gradient with suppressed conductivity detection. The selectivity of the Dionex IonPac AS19-4μm column 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.

The smaller resin particles used in the Dionex IonPac AS19-4μm column produce a backpressure over 3000 psi at the standard flow rates. A high-pressure IC system, such as the Dionex ICS-5000+排列5走势图 HPIC or the Dionex ICS-4000 Capillary HPIC system is required.

排列5走势图Note: Use the Thermo Scientific Dionex AERS 500 Anion Electrolytically Regenerated Suppressor with the Dionex IonPac AS19-4μm column for eluent suppression.
