Thermo Fisher, 303148, Dionex™ IonPac™ AS31 Analytical and Guard Columns

Name: Dionex™ IonPac™ AS31 Analytical and Guard Columns
Brand: Thermo Fisher
SKU: 303148

Length (Metric): 50 mm, Column Type: Guard Column, Unit Size: Each, 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 a

Description

Length (Metric): 50 mm
Column Type: Guard Column
Unit Size: Each
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 systemA 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.
