The Noble Gas facility is a research laboratory dedicated to the analysis of noble gases in samples, whether (1) solid (e.g. rocks and minerals from the terrestrial mantle and crust), (2) liquid (water and underground fluids) or (3) gaseous (e.g. atmospheric, volcanic, or geothermal gases).
These analyses are performed by (1) extraction (grinding, ablation using a 193-nm laser, and heating by induction and diode or CO2 laser), (2) purification under ultra-high vacuum (UHV) and (3) analysis by high-resolution mass spectrometry. The facility, installed at the CRPG, is part of the local ANATELo and ICÉEL (Institut Carnot) networks and, nationally, the RéGEF (INSU) network.
The facility is accessible to all CRPG researchers and each year welcomes masters and doctoral students and post-docs, as well as invited collaborating researchers. It is possible, upon validation by our steering committee, to provide services for other laboratories, whether academic or private.
