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 V Advantage Isotope Ratio Mass Spectrometer (IRMS)
Dataset-specific description

The N and O isotopic composition of N2O was then measured on a Delta V Advantage Isotope Ratio Mass Spectrometer (IRMS) interfaced with a modified Gas Bench II gas chromatograph (Thermo Fisher) purge and trap system.

Data was acquired from an isotope ratio mass spectrometer using Isodat 3.0 software.
