Thermo Scientific Dionex IonPac AS24A Hydroxide-Selective Anion-Exchange 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.

IonPac AS10 Hydroxide-Selective Anion-Exchange ColumnFor Isocratic and Gradient Separation of Inorganic Anions and Organic AcidsThe IonPac® AS10 is a high-capacity hydroxide-selective, anion-exchange column designed for isocratic and gradient separation of inorganic anions and organic acids. The column provides excellent resolution of weakly retained low-molecular-weight aliphatic acids. The high capacity of the AS10 permits the analysis of trace-level analytes in high-ionic-strength matrices. Use the AS10 column for analysis of inorganic anions in high nitrate samplesThe column provides excellent resolution of weakly retained low-molecular-weight aliphatic acids. The selectivity and high capacity of the AS10 permits the analysis of trace-level analytes in high-ionic-strength matrices. The AS10 resin strongly retains nitrate, which makes this column well suited for the analysis of trace anions in nitric acid and nitrate salts.Use with the Eluent Generator for simplified eluent preparation for applications using less than 100 mN hydroxide.
