Abstract

The method is based on liquid chromatographic separation of ions (low capacity anion exchanger as the stationary phase, and usually aqueous solutions of salts of weak monobasic and dibasic acids as mobile phases), detection by a conductivity detector, sometimes employed in combination with a suppressor device (e.g. a cation exchanger) which decreases the conductivity of the eluent and converts the separated anions into their corresponding acids. Admissible contamination is given for each anion. Water with low contamination means e.g. drinking water, rain water, ground water, and surface water. Interferences are also indicated.
