Includes bibliographical references (page 8). "Organic acids originating from biogenic and anthropogenic sources are now known to play an important role in environmental chemistry. Both organic and inorganic acids need to be determined accurately in order to properly explain atmospheric chemistry processes and precipitation ionic balances. This report describes an isocratic anion chromatographic method for the analysis of samples containing these acids and assesses its performance against that of a gradient method and an ion-exclusion method. The assessment results show that in order to adequately determine all acids of concern, the gradient and ion-exclusion methods should be jointly used to analyse precipitation samples"--Management Perspective.
