Radiogenic, non-traditional stable & rare gas isotopes. Le Centre de Recherches Pétrographiques et Géochimiques (CRPG), Nancy, France:
The CRPG is a joint facility of the Centre National de la Recherche Scientifique and University of Lorraine comprising ~100 people (including support staff and students) working in the field of Earth and Planetary Science. It hosts two national analytical facilities, the Service for the Analysis of Rocks and Minerals (Service d'Analyse des Roches et des Minéraux - SARM -) and the ion probe facility. Research undertaken at the CRPG includes the origin of matter in the Solar System, processes and timing of planetary formation, environments of early Earth, biogeochemical cycles: fluxes and compositions of the ocean and atmosphere as well as coupling between tectonic, topography, erosion and climate. CRPG is a NASA host laboratory for lunar samples and has worked on material from all return missions (Apollo, Luna, Genesis, Stardust, Hayabusa) playing a leading role noble gases and volatile element analysis. The CRPG is one of the few laboratories worldwide to analyse nitrogen isotopes in igneous rocks and helium for dating surfaces with cosmic ray-produced 3He.
Ion probe facility (Cameca ims 1270-MC and Cameca ims 1280). - The Cameca 1270 Ion microprobe is a CNRS-INSU national facility, upgraded in 2014 to match the capabilities of the recently installed ims 1280. Routine analyses include U-Pb dating on zircon, monazite or pitchblende, C, O, Si isotope ratios and light and trace elements contents of different matrixes. A notable speciality is the measurement, at high precision, of the isotopic ratios of light elements (H, Li, N, Mg, S) including mass independent fractionation of sulphur isotopes.
Helium and Nitrogen isotope facility. (1 VG 5400, 1 VG 603, 2 Helix SFT, 1 Helix MC and 1 GV Noble). -Helium isotopes determined on meteorites and ET return samples, for surface exposure dating with cosmogenic 3He using the latest He isotope mass spectrometer, the GV Helix SFT, the first instrument of its kind installed in Europe. Analysis of nitrogen at the nanomol level in rocks, minerals and ET return samples is used to fingerprint volatiles and reconstruct magma degassing.
Stables Isotopes: ThermoFinnigan Neptune Plus MC-ICPMS, ThermoFisher MAT253 and GV Isoprime provide the capability for C, O, S, H isotope analyses of rocks, minerals, organic matter and fluids (water, natural gases) by continuous flow mass spectrometry coupled with elemental analyser or off line extraction and "novel" stable isotopes by sector field ICP-MS (Neptune+). This includes O isotopes on silicates by fluorination and H, C & O on fluids from single inclusions. The determination of high precision Mg, Ca, Fe and Ge isotopes is offered and this is something only available in a handful of labs in the world.
 
Radiogenic Isotopes determined by TIMS (FinniganMat 262 & ThermoFinnigan Triton) include Os isotopes and the extinct system 146Sm-142Nd (only developed in a handful of labs worldwide) and Sr-Nd-Pb isotopes that are the “traditional” isotopic systems in meteorite, lunar and terrestrial rock studies.
