文摘
- •
A new large-radius high-mass resolution gas-source isotope ratio mass spectrometer is described.
- •
The instrument affords a mass resolving power of over 60,000.
- •
Measurements of rare isotopologues of gases, including CH4, N2 and O2 are accessible with the new instrument.
- •
Separation of 13CH3D and 12CH2D2 is highlighted.
