Achieve high resolution separations of trace oxyhalides and inorganic anions in drinking water using the Thermo Scientific™ 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, this anion-exchange column uses smaller resin particles for more efficient separations resulting in more accurate peak integration and more reliable results.

Easy Method Transfer
With similar selectivity and increased peak efficiencies, you can easily transfer applications from the Dionex IonPac AS19 column to the Dionex IonPac AS19-4μm column.

Significantly Reduce Eluent Usage
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 4mm 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.

Dionex IonPac AS19-4μm Capillary Column Features
  • Choose from three formats: 4×250mm, 2×250mm and 0.4×250mm
  • Recommended hydroxide-selective column for trace bromate in drinking water matrices
  • Meets or exceeds performance requirements of US EPA Method 300.0 and US EPA Method 300.1
  • High capacity: 240μeq per column (4×250mm)
  • Column selectivity is optimized for 30 °C operating temperature
  • Compatible with organic solvents
These capillary columns require high pressure Thermo Scientific™ Dionex™ ICS-5000+ or Dionex ICS-4000 HPIC™ system to run at standard flow rates.
