(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: Delta Advantage isotope ratio mass spectrometer
Dataset-specific description

Filters were weighed into tin capsules and analyzed for 13C/ 12C ratios with an automated Isotope Cube elemental analyzer (Elementar, Germany) interfaced to a Delta Advantage isotope ratio mass spectrometer (Thermo, Germany).
