Area(s) of Expertise

The laboratory’s customers are from fields such as geology, biology, environment, geography and kinanthropology. The laboratory’s mission in the field of stable isotopes has tripled in scope in more than 30 years. Its mission is now to train undergraduate and graduate students, participate in cutting-edge research and provide service to external customers. Specifically, the laboratory performs analyses of stable isotopes of hydrogen (1H, 2H), oxygen (16O, 17O, 18O), carbon (12C, 13C) and nitrogen (14N, 15N) on a variety of organic and inorganic samples. The laboratory’s main projects are numerous: paleoclimatology, physical effort, ocean biogeochemistry, ocean circulation, hydraulic and biogeochemical tracing in big rivers, carbon cycle in peat bogs, soil biogeochemistry, paleonutrition, ancient population movement, detection of agri-food fraud, etc.
