Hydrogen by IRMS

  •  δD values of water and water extract samples are determined in dual inlet (DI) using a hot chromium reactor unit (H/Device™) interfaced with a Thermo Delta V Plus mass spectrometer. We add multiple standards  to every run and we correct for differential drift of standards with different isotope ratios. Long-term external precision ± 0.60‰.
  • Sample size:   We recommend a sample size of at least 50 μL and preferable 1 mL of water.
