It is equipped with 9 Faraday cages allowing the simultaneous acquisition of 9 isotopes; as well as a RPQ filter coupled to an electron multiplier SEM for the acquisition of weak signals.

It is also equipped with 1 1010 Ohms amplification board, 9 10¹¹ Ohms amplification boards, 2 10¹² Ohms amplification boards, 7 10¹³ Ohms amplification boards and 2 gain calibration boards (3.33V and 0.33V). These cards are easily interchangeable thanks to the new amplification block developed by ThermoFisher Scientific.

• in cosmochemistry :

• • measurements of Samarium / Neodyme system 146,147Sm-142,143Nd and 138La-138Ce on meteorites and lunar samples
  • Stable isotope measurements of Neodymium (Nd) and Samarium (Sm) to detect nucleosynthetic anomalies and isotopic variations induced by cosmic rays.

• The study of the evolution of the composition of the Silicate Earth with the coupling of the La-Ce and Sm-Nd isotopic systems.

• Development in progress: measurement of stable isotopes of Neodymium (Nd), Samarium (Sm) and Strontium (Sr) in very small quantities.

This instrument is part of the French Geochemical and Experimental Network (REGEF).
The Laboratory also has another TIMS: a Triton – ThermoFisher Scientific
