AN149: Determination of Chlorite, Bromate, Bromide, and Chlorate in Drinking Water by Ion Chromatography with an On-Line-Generated Postcolumn Reagent.

Instrument Type: IC

This application note describes an improved ion chromatography (IC) method to quantify oxyhalide DBP anions and bromide at low concentration levels in reagent water, bottled water, and finished drinking water using an approach that is technically equivalent to U.S. EPA Method 326.0. The oxyhalide anions chlorite, chlorate, bromide, and bromate are separated on a Thermo Scientific Dionex IonPac AS9-HC column and measured by using suppressed conductivity detection (as in EPA Method 300.1), followed by postcolumn reaction (PCR) to enhance detection of bromate.

Fast Determination of Anions in Bottled Water

Instrument Type: IC

Inorganic anions in mg/L concentrations in bottled water sample were seperated using a 2 x 150 mm, IonPac AS18-Fast anion-exchange column designed for fast separation using electrolyticallly generated hydroxide eluents.
