的詳細介紹
Thermo Scientific Dionex IonPac AS24A Hydroxide-Selective Anion-Exchange Column
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.
