- Triple collector continuous flow IRMS (Isotope Ratio Mass Spectrometer) devoted specifically for 17O/16O and 18O/16O ratio analysis using O2 as a measuring gas and He as a carrier gas. Refinement is under way.
- Required sample size is less than 1μg.
- On-line Ar-F laser-assisted fluorination system for O2 extraction is attached.
- Precise δ17O and δ18O analysis of mineral constituents of meteorites, with an error less than 0.5 ‰ and spatial resolution of 100 µm.
