Visiting Kochi University (Japan)
Our portable mass spectrometer arrived safely at the Center for Advanced Marine Core Research of Kochi University hosting one of the IODP core repositories . Sunday Feb. 12th was dedicated to some sightseeing.
For our first international project the miniRUEDI underwent the custom procedures at Zurich Airport and it is now ready to fly to Japan!
Please enjoy the first research article of Nature Water which underlines the potential of on-site gas analyses in combination with other environmental tracers:

Today we started the first gas sampling campaign planned in 2022 at the HotBENT experiment (Grimsel Test Site). For this purpose, Entracers prepared additional samplers that will be available for future projects of our customers.
A collaborative research project involving the Swiss Federal Institute of Aquatic Science and Technology, the Institute of Geological Sciences at the University of Bern, and Posiva Oy targeted gas-bentonite interactions in relation to the gas dynamics in Engineered Barrier Systems. The outcome of the study has been published in the following open access article:
- Tomonaga, Y., Wersin, P., Rufer, D., Pastina, B., Koho, P., Ville, H., & Kipfer, R. (2022). Gas-bentonite interactions: Towards a better understanding of gas dynamics in Engineered Barrier Systems. Appl. Geochem., 138, 105205, doi:10.1016/j.apgeochem.2022.105205.
Interested in conducting further investigations based on the same methods? Entracers GmbH can now provide the required know-how as well as the related analytical facilities!
On Jan. 15th 2022, while running test measurements, our miniRUEDI was able to catch the pressure wave produced by the Hunga Tonga volcanic eruption.
The first miniRUEDI of Entracers is ready to perform gas measurements for the GAST experiment at the Grimsel Test Site. We are looking forward to the developments of this project managed by Nagra!
Let’s call it “Christmas present”: Entracers is now the proud owner of the first patented (or, more precisely, “pat. pending”) GE-MIMS module which allows quantitative gas analysis in water using the miniRUEDI. Such Eawag-patented GE-MIMS modules can be purchased at Gasometrix GmbH.
New gas samples were collected by Entracers from the Full-scale Emplacement (FE) experiment on Nov. 11th-12th, 2021. This was the first sampling planned for Phase 27 of the Mont Terri Project.
A picture of Entracers “in action” can be found in the Mont Terri Rock Laboratory field report.
