Thermo Fisher, 303147, Dionex™ IonPac™ AS31 Analytical and Guard Columns

Analytical Column, 250 mm, 6 μm 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. Anion Exchange Capacity: 116 μeq
