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.
Compared to the Thermo Scientific™ Dionex™ IonPac™ AS23 columns, these columns use smaller resin particles for more efficient separations resulting in more accurate peak integration and more reliable results.
Higher resolution is achieved through the use of smaller resin particles, which produce a column backpressure over 3000psi at the standard flow rates. A high-pressure IC system, such as the Thermo Scientific™ Dionex™ ICS-5000+ HPIC™ or the Thermo Scientific™ Dionex™ Integrion™ HPIC™ system is required to operate this column under standard conditions and take advantage of elevated flow rates and faster run times.
Note: Use the Dionex AS23 Eluent Concentrate for simple, accurate eluent preparation.
