Dionex™ IonPac™ AS31 Analytical and Guard Columns

Catalog number: 303147

Achieve faster separation of haloacetic acids (HAAs), bromate, and dalapon in drinking water prior to detection with ion chromatography (IC) and mass spectrometry (MS) with the new Thermo Scientific™ Dionex™ IonPac™ AS31 column. Specifically designed for fast analysis, the Dionex IonPac AS31 provides approximately 39% shorter run times relative to the Dionex IonPac AS24, reducing U.S. EPA Method 557 run time from 57 minutes to approximately 35 minutes. This new hydroxide-selective anion-exchange column has relatively high capacity to allow large loop injections for trace analysis (μg/L) without sample pre-treatment.

Superior Chromatographic Performance
  • Can meet or exceed the performance requirements of U.S. EPA Method 557.
  • High capacity (116 μeq/column) allows injection of complex matrices without overloading the column while maintaining excellent peak shapes for lower concentration analytes.
  • Requires no sample pre-treatment when determining haloacetic acids in high-ionic strength matrices.
  • Column selectivity has been optimized at an operating temperature of 15°C to ensure reproducible recovery for haloacetic acids.
Use with a High-Pressure IC system

A high-pressure IC system, such as the Thermo Scientific™ Dionex™ ICS-5000+ HPIC™ system or Dionex ICS-6000 HPIC system is required to operate this column under standard conditions.
