AN31: Determination of Anions in Acid Rain by Ion Chromatography

Instrument Type: IC

This application note describes the established ion chromatographic method for the determination of anions in rainwater samples extended to the use of microbore columns and accessories. A rainwater standard from the National Institute of Standards and Technology (NIST) was analyzed, verifying the accuracy of the method. This method is updated in AU146 to include the use of electrolytic eluent generation and the IonPac AS18 column.
