There are many methods currently available for the assay of sulfate and nitrate in ambient aerosols. These methods appear to be inadequate because of poor sensitivity and/or selectivity or are cumbersome to use. H. Small, T.S. Stevens and W.C. Bauman recently reported a new technique called ion chromatography (IC). The technique, uses ion exchange chromatography, eluant suppression, conductimetric detection and is ideal for the analysis of sulfate and nitrate in ambient aerosols. Ion exchange chromatography with conductimetric detection has been attempted in the past for the assay of anions and cations with little success because of the high background produced by the electrolyte or eluant used. Dr. Small used a novel technique of eluant. This communication describes the first successful application of ion chromatography to the analysis of sulfate and nitrate in ambient aerosols.
