Instrument: Isotope-ratio Mass Spectrometer

Instrument Short Name: IR Mass Spec; IRMS
(http://vocab.nerc.ac.uk/collection/L05/current/LAB16/)
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: Micromass Isoprime continuous flow stable isotope mass spectrometer
Dataset-specific description

Dried samples of basalt (20–70 mg) were placed into tin foil capsules for isotopic analysis of 13C/12C ratios. Samples were analyzed using a Costech elemental analyzer in line with a Micromass Isoprime continuous flow stable isotope mass spectrometer.
