Assessing the hyphenation of ion chromatography with optical emission spectrometry for trace analysis of oxyhalide bromine and chlorine species

For the first time, Br and Cl speciation was successfully achieved by using IC-ICP-OES hyphenation. The results highlight the robustness and applicability of the developed method exemplarily for oxyhalide speciation, clearly differentiating species-specific behavior of halogens in an emission spectrometer. This hyphenation technique generally enables solving complex separation problems by simultaneously evaluating different spectral properties, hence demonstrating to be a valid alternative to ICP-MS, especially for pool and spa water quality monitoring.
