 Sulfur Isotope Analysis (34S/32S, δ34S)
Sulfur isotope analysis of organic solids and liquids are analyzed using an elemental analyzer (EA) coupled to an isotope ratio mass spectrometer (IRMS). Sulfur isotopic compositions can be carried out on the hydrogen sulfide (H2S) fraction in a gas mixture by ZnS precipitation followed by EA-IRMS analysis.
