Abstract
In this work we developed an analytical method for precise and accurate analysis of δ34S, δ81Br, and δ37Cl in individual anionic species by coupled ion chromatography (IC) and multicollector inductively coupled plasma mass spectrometry (MC-ICPMS). The method is based on the online separation and purification of ions by IC prior to their isotope analysis by MC-ICPMS. The developed technique significantly simplifies δ34S, δ81Br, and δ37Cl analysis in environmental samples. In cases when several anionic species of the same element are present in the sample, they might be analyzed in a single analytical run. The description of the method will be presented as well as examples of the applications to environmental studies such as isotopic analysis of perchlorate and different sulfuric species.
