AN187: Determination of Sub-µg/L Bromate in Municipal and Natural Waters
Description
In this application, we demonstrate the use of a 2-D IC system to determine trace bromate concentrations in waters with high ionic strength matrices. The first dimension uses a high capacity 4-mm Thermo Scientific™ Dionex™ IonPac™ AS19 column to resolve the bromate from the matrix ions. The matrix ions are diverted to waste while a 2 mL plug is transferred to the 2-mm Thermo Scientific™ Dionex™ IonPac™ AS24 column. This method is fully automated and achieves comparable or improved sensitivity and lower cost than postcolumn addition methods.| Market: | Environmental |
