A rapid and high‐precision method for sulfur isotope δ34S determination with a multiple‐collector inductively coupled plasma mass spectrometer: matrix effect correction and applications for water samples without chemical purification

Abstract: The data and the results indicate that it is feasible to use MC-ICP-MS and matrix-matched working standards to measure the sulfur isotopic compositions of water samples directly without chemical purification. In comparison with the existing MC-ICP-MS techniques, the new method is better for directly measuring δ(34)S values in water samples with complex matrices; therefore, it can significantly accelerate analytical turnover.

“…At the least, the pore water obtained in this way can be analyzed for sulfate concentrations. With a combination of elaborate sulfur extraction techniques (Arnold et al, 2014) and high sensitivity isotope analysis by multi-collector ICPMS (Paris et al, 2013;Lin et al, 2014) it might even be possible to measure the sulfur isotope composition of sulfate. However, in light that barite dissolution in sulfate-free seawater would yield a sulfate concentration <20 µM researchers must brace themselves for extremely low sulfate concentrations for sulfur and oxygen isotope analyses.…”

“…While the use of ion selective resin is useful to pre-concentrate sulfate in fresh-water samples [22-24], the resin based method remains unfavorable in marine and marine-type media due to the high and close affinity of the resin for chloride and sulfate. Recently, the use of multiple collector – inductively coupled plasma mass spectrometry (MC-ICPMS) has been developed for the analysis of extremely small quantities of sulfate [25,26]. Although sulfur isotope analysis by MC-ICPMS lowers the detection limit for sulfur isotope analysis by several orders of magnitude (down to ~5 nmol S), the sample preparation prior to the MC-ICPMS analysis still requires resin based chemistry and there are less than a handful of facilities that specialize in this instrumentation and methodology [25,27].…”
