Dionex™ IonPac™ AS23-4µm Analytical and Guard Columns

Analyze trace bromate and other oxyhalides in drinking water, ground water, wastewater, and other diverse matrices using the Thermo Scientific™ Dionex™ IonPac™ AS23-4µm columns. The high capacity and selectivity of this column facilitates the determination of trace bromate at low-µg/L levels in the presence of high amounts of chloride, sulfate, and carbonate. Compared to Dionex IonPac AS23 column, the new Dionex IonPac AS23-4µm columns use smaller resin particles for more efficient separations resulting in more accurate peak integration and more reliable results.
