Instrument Description:

The Isotope-ratio Mass Spectrometer is a particular type of mass spectrometer used to measure the relative abundance of isotopes in a given sample (e.g. VG Prism II Isotope Ratio Mass-Spectrometer).

PI supplied instrument name: GV/Micromass IsoProbe multicollector ICPMS
Dataset-specific description

Nobias Chelate PA1 preconcentration followed by anion exchange purification: This method starts with a new double batch ion-exchange chelation preconcentration followed by the Reuer et al. (2003) anion exchange purification followed by isotope ratio analysis on a GV/Micromass IsoProbe multicollector ICPMS.
