GENESIS

Presentation of the Platform

The GENESIS analytical platform is dedicated to determining the isotopic compositions of Oxygen (δ¹⁸O), Carbon (δ¹³C), Hydrogen (δ²H), Nitrogen (δ¹⁵N), and Sulfur (δ³⁴S) in solid and liquid matter. It analytically supports the research activities of the 4PAL, BVP, and Surface and Lithosphere themes. This platform is divided into several dedicated workspaces: sample preparation, wet chemistry, clean chemistry, precision weighing, as well as an analysis room equipped with isotope ratio mass spectrometers (IRMS). The platform’s operations are managed by a research engineer and a technician.
