Stable isotope ratio mass spectrometers VG SIRA10 for δD measurement

VGSIRA10 for D
VG SIRA10 for δD measurement

machine specifications:

  • Dual inlet, double collector IRMS (Isotope Ratio Mass Spectrometer) devoted specifically for D/H ratio analysis using H2 as a measuring gas
  • Required sample size normally 100 μl H2, or 2 mg H2O.
  • On-line Cr reduction system for δD analysis of water.


  • High precision δD analysis of water and rocks including hydrous silicate minerals with precision better than 0.5 ‰. Refer to preparation systems.
