The effect of eluent pH and eluent species concentration on the nonsuppressed ion chromatographic separation of anions has been studied. The retention times of Cl/sup -/, Br/sup -/, NO/sub 3//sup -/, SO/sub 4//sup 2 -/, and S/sub 2/O/sub 3//sup 2 -/ were determined over a large range of eluent compositions and the data were utilized to construct window diagrams. These window diagrams were used to optimize eluent composition for the separation of two or more analytes. In virtually every case resolution is limited by the separation of the NO/sub 3//sup -//Br/sup -/ pair. 10 references, 5 figures, 2 tables.
