Instrument: Mass Spectrometer
General term for instruments used to measure the mass-to-charge ratio of ions; generally used to find the composition of a sample by generating a mass spectrum representing the masses of sample components.
Neodymium was measured as NdO+ on a VG TIMS Sector ( at UH) and VG TIMS Sector54 ( at LDEO). At USC, the Nd isotope composition was measured on a Thermo Neptune Plus MC-ICPMS.
