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: Elementar Isoprime visION
Dataset-specific description

The d15N of tow-collected, size-fractionated PON was determined by elemental analyzer-isotope ratio mass spectrometry (an Elementar Vario Isotope Cube online to an Elementar Isoprime visION), referencing to atmospheric N2 using USGS-40 and an in-house aminocaproic acid standard.
