The LMCM (the Muséum Laboratory of Mineralogy and Cosmochemistry, UMR 7202 CNRS/MNHN) is home to the latest generation of ion probes - the NanoSims 50 (SIMS: Secondary Ions Mass Spectrometry). This instrument produces isotopic maps with a 100 nanometre spatial resolution. It is available to users outside the Muséum national d’Histoire naturelle under the National INSU Service (CNRS).
The NanoSims is placed on an analytical platform which also has a SIMS 3f ion probe and a Scanning Electron Microscope (SEM). These two instruments supplement the NanoSims analysis of terrestrial and extraterrestrial samples. In particular, the SEM chemically maps the zones to be analysed with the NanoSims. The 3f probe is used for routine spot analyses, particularly for the concentration and isotopic composition of hydrogen.

Isotope-ratio Mass Spectrometry Service
The SSMIM (Muséum’s Isotope-ratio Mass Spectrometry Service) is located within the isotopic analysis platform, on the ground floor of the Mineralogy building, 61, rue Buffon (Paris 5th arrondissement). It is dedicated to issues regarding historical and prehistoric anthropology, for the purpose of paleo-environmental, paleo-climatic and paleo-diet reconstructions.
The Isotope-ratio Mass Spectrometry Service has two pieces of analytical equipment:
- an automated preparation device (Kiel IV) interfaced with an isotope-ratio mass spectrometer (DeltaV Advantage) for the analysis of δ13C and δ180 in carbonates (commissioned in 2006). This equipment can be used for isotope dosages on bicarbonates (bones and teeth of mammals including rare human and animal fossils, fish otoliths, mollusc shells and corals) and carbonates (speleotherms and soils).
- an elemental analyser (Flash 2000) interfaced with an isotope-ratio mass spectrometer (DeltaV Advantage) for the analysis of δ13C and δ15N in organic matter (commissioned in 2009). In the field of anthropology, the samples are mainly of collagen, keratin and plants.
