The MC-ICP-MS and TIMS Mass Spectrometry facility is dedicated to high-precision isotopic analyses of geological, extraterrestrial or environmental samples. This includes the development of new tools based on variations of the isotopic abundances of stable (mass-dependent or -independent) or radiogenic isotopes.
We use these tools for different projects within the Sciences of the Earth and the Universe: the formation of the Earth and the solar system, geochronology, magmatic processes, differentiation of the mantle, continental alteration, (palaeo)environmental reconstructions, or even characterising pollution and the influence of human activities.
The principal instruments within our facility include a Neptune Plus MC-ICP-MS, a Triton Plus TIMS and a Finnigan MAT 262 TIMS. We also have an ensemble of clean rooms as part of the project STEHLo.
This facility, installed at the CRGP, is part of the local ANATELo network (OSU OTELo) and the national RéGEF network (INSU). It is also part of the SGRIF facility of the Europlanet network.

Clean rooms – STEHLo facility
Description:
Upstream of sample isotopic analyses (including, for example, meteorites, igneous rocks, sediments, river waters or plants), the chemical elements of interest must be extracted from their natural matrix. This involves digesting them, i.e. putting them in solution, then extracting them by different methods (ion exchange resin, distillation, liquid-liquid chromatography).
Analyses:
In addition to well-established analyses (e.g. Rb-Sr, Sm-Nd, Pg-Pb and Lu-Hf dating or even tracing sources using 87Sr/86Sr or ε148Nd), we develop new methods for specific isotopes, whether stable or radiogenic (e.g., Δ33S, ε40Ca, δ74Ge, 186Os/188Os, ε143Nd ou encore δ148Nd).
This ensemble of clean rooms is grouped under the project STEHLo.
CONDITIONS OF ACCESS/PRICES
Access: Access to this facility requires prior training. Annually, our facility welcomes masters and doctoral students (mainly from the Faculté de Sciences et Technologie de l’Université de Lorraine and l’Ecole Nationale Supérieure de Géologie) and postdocs. We also provide services to our academic collaborators and private partners. Do not hesitate to contact the SARMi (Sr, Nd, Pb) or the facility managers (by email or the below contact form) for more information concerning other elements or isotopic systems.
Prices: Contact the facility managers.
