Within the frame of a collaborative work involving the Eawag, the University of Basel, Nagra, and the University of Bern it was possible for the first time to date sediments deposited during the early Chibanian (Middle Pleistocene) using the ⁴He/U-Th medod. The respective article accepted by Geology and is freely available at the following address:

Tomonaga, Y., Buechi, M.W., Deplazes., G., & Kipfer, R. (in press). First dating of an early Chibanian (Middle Pleistocene) glacial overdeepening in the Alpine Foreland using the 4He/U-Th method. Geology, doi:10.1130/G52544.1.

At Entracers we now have all the know-how and technical means to apply the newly developed method applied to determine the radiogenic ⁴He concentrations in the pore water of coarse/semi-consolidated sediments as those found in the Hochfelden-Strassberg drilling!

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.

After a couple of months Entracer’s first portable membrane inlet mass spectrometer system (aka miniRUEDI) is ready to determine gas concentrations in the environment. A few applications that exemplify the flexibility of this instrument:

Long-term monitoring of the gas composition in a trial run for radioactive waste disposal (Tomonaga et al., 2019, Appl. Geochem.)
Targeting the gas-clay interactions in laboratory trials (Giroud et al., 2018, Appl. Geochem.)
Determine changes in the noble-gas composition at CO₂ capture plants (Weber et al., 2021, Int. J. Greenh. Gas Con.)

Testing the miniRUEDI

Many thanks are due to Matthias Brennwald at Gasometrix GmbH for supporting its construction!

The first “serious” piece of equipment is growing! You can guess what is this device…
