The Max Planck research group for Marine Isotope Geochemistry uses a ThermoScientific Neptune Plus multi-collector inductively-coupled plasma mass spectrometer (MC-ICP-MS) for the precise analysis of isotope ratios of trace elements. The instrument is equipped with 9 Faraday detectors (8 of which are moveable) for the simultaneous analysis of up to 9 diferent masses, and a secondary electron multiplier (SEM) for the analysis of very low signal intensities.
The instrument is currently set up to routinely measure stable and radiogenic isotopes of the elements Nd, Sr, Pb and Si in seawater, porewaters, suspended particles and marine sediments.
The seaFAST pico (ESI, Elemental Scientific) allows the automated preconcentration of trace elements from seawater. For the first time, we can now measure rare earth element concentrations in as little as 10 mL of seawater, which previously required 100-1000 mL samples (see Behrens et al., 2016.
