The main application of the mass spectrometer is the analysis of stable isotope ratios in a wide range of materials. We focus on stable metal(loid) isotope analysis of Li, Mg, Si, Fe, and Sr isotopes, but are – in principle – capable of measuring other systems. Alternatively, to solution MC-ICP-MS, a femtosecond laser ablation system can be coupled to the MC-ICP-MS for (in situ) micro scale isotope ratio analysis of solid samples.
Inductively Coupled Plasma Multicollector Mass …

The Isotope Geochemistry Labs are equipped with a clean room facility (including several low-blank chemistry laboratories (class 100), sample preparation and ion-exchange chromatography, a set up for isotope systems: Pb, U-Pb, Rb-Sr, Sm-Nd as well as B and Li isotopes), two thermal ionization mass-spectrometers (TIMS) and a multi-collector mass-spectrometer with inductively coupled plasma source (MC-ICP-MS).

In June 2022, a new Mass Spectrometer was installed in the Geochemistry labs at the Institute of Geological Sciences, Freie Universität Berlin. The Neoma instrument represents a new generation of MC-ICP-MS instruments, and its acquisition was jointly funded by the DFG and Freie Universität Berlin to support TRR 170 research. It provides various technical advances that result in excellent sensitivity, large mass dispersion and enhanced mass …
