The Stable Isotope Laboratory is installed with isotope ratio mass spectrometers MAT252, MAT253, Delta S and Delta V, and has established eight pretreatment and purification systems for isotopes of different elements. Using these instruments and systems, the laboratory is capable of analyzing stable isotope ratios of C, S, H, O, N, Si and Ar from a range of materials including minerals, rocks, fluid inclusions, soil, water, gases, petroleum, plants and organic compounds.
