          Thermo Scientific Dionex IonPac AS24A Hydroxide-Selective Anion-Exchange The Thermo Scientific™ Dionex™ IonPac™ AS24A is a high-capacity hydroxide-selective anion-exchange

          詳細(xì)介紹

          For Separation of Haloacetic Acids and Bromate in Drinking Water 

          The Thermo Scientific Dionex IonPac AS24A is a high-capacity hydroxide-selective anion-exchange column optimized for the separation of haloacetic acids (HAAs) as well as a variety of environmental anions. The capacity and selectivity enables analysis of haloacetic acids in drinking water at low-μg/L concentrations. The Dionex IonPac AS24A 4 × 250 mm column is specifically designed for the first dimension separation of haloacetic acids in drinking water prior to the second dimension separation using the Dionex IonPac AS26 capillary column, followed by suppressed conductivity detection. The Dionex IonPac AS24A column is ideal for the development of specialized applications, including 2D-IC, providing excellent separation of environmental anions including inorganic anions, oxyhalides, oxyanions, and organic acids. The high capacity of the Dionex IonPac AS24A column allows injection of complex matrices without overloading the column while maintaining excellent peak shapes for lower concentration analytes. The Dionex IonPac AS24A capillary column offers users excellent retention time reproducibility and in addition, increased mass sensitivity and eluent conservation.

          • High capacity: 560 μeq per column (4 × 250 mm)

          • Determine HAAs in high-ionic strength matrices without sample pretreatment

          • Column selectivity is optimized for a 15 ºC operating temperature

          • Compatible with HPLC organic solvents

          • Used as first dimension column in 2D-IC method for haloacetic acids (4 × 250 mm)

          • Extended application capabilities providing excellent separation of environmental anions
