Update of AN151: Determination of Perchlorate in a Drinking Water Sample Using a Compact Ion Chromatography System Coupled to a Mass Spectrometer Be the first to rate this application


Perchlorate, an industrial contaminant from rockets, munitions, and fireworks, causes thyroid dysfunction in humans, especially pregnant women and children. In 2002, the EPA recommended a Provisional Reference Dose for perchlorate of 1 µg/L in drinking water. In 2015, California established a MCL of 6 µg/L with a Public Health Goal of 1 µg/L. IC-MS can provide lower detection limits (~ 30 ng/L) than conductivity in high-ionic-strength matrices using the MS selectivity at 99/101 m/z. Here we update AN151 with the Integrion IC system combined with the MSQ Plus mass spectrometer.
