Ion Chromatographic Analysis of Sulfate and Nitrate in Ambient Aerosols

摘要: Abstract Ion exchange has been known to provide excellent separation of ions since 1850, and ion chromatography in use 1940. However, not widely used for the automated analysis eluted because background produced by electrolyte elution. H. Small, T. S. Stevens, W. C. Bauman, (Anal. Chem., 47, 1801 (1975)) recently developed a technique whereby is reduced minimum with eluant suppression. Eluant suppression allows conductimetric detection as sensitive selective means practically all ionic species. This communication describes first successful application (IC) total water soluble sulfate nitrate ambient aerosols. Analytical conditions data on sensitivity, selectivity, accuracy repeatability are described. The this atniospheric ...
