Multicollector mass spectrometer for isotopes

Installed in February 2024, our Neoma MS/MS is the latest in multicollector mass spectrometers. Equipped with a prefilter and collision cell, it allows chemical separations on the fly, opening the doors to do, for example, single laser spot age dating by Rb/Sr, while still performing the methodologies we have had in use in the laboratory since 2008.

Three white laboratory devices stand on their feet in the room.

Methodologies in use include:

  • Age dating – in situ U-Pb
  • Zircon, monazite, titanite, xenotime
  • Sulfur & copper isotopes – in situ on sulfides
  • Li, Mg, Sr, Pb, U – on waters and single element solutions
  • Sr isotopes – in situ on plagioclase
  • Pb isotopes – in situ on K-spar, sulfides, tellurides
  • Hf isotopes – in situ on zircon
  • U series – on single element solutions
