Abstract
In order to verify that measurements of the 15N2 atom% of dissolved N2 gas samples effectuated by Membrane Inlet Mass Spectrometry are accurate, we compared these to corresponding measurements of parallel samples on a Delta V Isotope Ratio Mass Spectrometer (IRMS). To this end, we first ensured that the IRMS returns accurate 15N2 atom% values, by measuring the 15N2 atom% of a serial dilutions of a 15N2 gas stock in air and helium. This calibration is documented herein, showing that IRMS measurements in the experimental range were accurate, as expected For a complete list of measurements, refer to the full dataset description in the supplemental file 'Dataset_description.pdf'. The most current version of this dataset is available at: https://www.bco-dmo.org/dataset/778000
