Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references (page 7). "This report describes an ion 9 exclusion chromatographic method for simultaneous analysis of organic acids usually found in precipitation — related samples. The method "excludes" most strong inorganic acids and resolves most organic acids particularly lactic and acetic, which the powerful gradient method can not resolve. The analyzable acids are citric, hydrofluoric, lactic, glycolic, formic, acetic, propionic and butyric"--Management perspective, page i.
