Zinc/Silver‐Based Hydrogen Sulfide Trapping as an Alternative to Cadmium for Sulfur Stable Isotope Analysis
The Zn/Ag-based method produced δ<sup>34</sup>S values comparable with the Cd-based method and maintained accuracy with lower molar inputs of H<sub>2</sub>S. The minimum molar input for analysis is ~8.4 × 10<sup>-6</sup> mol. The Zn/Ag method is safer for human health and the environment, and a suitable alternative to Cd for H<sub>2</sub>S trapping and subsequent δ<sup>34</sup>S determination by IRMS.
