AN73342: Determination of Low-Level Haloacetic Acids, Bromate, and Dalapon in Drinking Water using IC-MS
Description
This AN evaluated an IC-MS method for the determination of all nine haloacetic acids, bromate, and dalapon in drinking water using a Dionex ICS-6000 HPIC system couple with an ISQ EC single quadrupole mass spectrometer. Dionex IonPac AS31 column was used. It found that the IC-MS method is fast (40 min vs. 60 min in Method 557) and linear. It is sensitive (<1 μg/L), accurate and precise for the determination of U.S. EPA regulated HAA5, bromate, and dalapon. Critical IC system conditions important for successfully running this application are included.| Market: | Environmental |
