Abstract

The usefulness of capillary electrophoresis in the analysis of inorganic and organic anions in atmospheric aerosols was investigated. Various electrolytes based on chromate, pyromellitate (PMA), phthalate and 2,6-naphthalenedicarboxylate (NDC) were tested. Two separate electrolyte systems (PMA and NDC) are recommended for determination of anions with different mobility. Results obtained by parallel analysis of sulphate by capillary electrophoresis and ion chromatography in atmospheric aerosols are presented.
