A sample is passed through a preparatory cartridge which removes the trisubstituted haloacetic acids that interfere with determination of bromate. The bromate in the sample is then separated from other compounds using an ion chromatography (IC) system. The concentration of bromate that is eluted from the IC system is measured using an inductively couple plasma/mass spectrometer (ICP/MS).
Applicable Conc Range 10 - 50 µg/L is suggested.
Detection limit: 0.3 µg/L
