Second gas sampling at the HotBENT experiment

On Oct. 28th 2021 Entracers collected new samples at the HotBENT experiment at the Grimsel Test Site that will provide the data basis to interpret future changes in the gas composition within the drift. After the sampling we enjoyed the nice autumn weather on the way back to Zurich.

Gas monitoring running at the completed HotBENT experiment

After the revision of one of the valves of the gas circulation system at the HotBENT experiment, on Sept. 16th 2021 the gas monitoring of all sampling ports within the drift was launched. This will allow observation of possible changes in the gas composition even during the early stages of the experiment.

Entracers’ miniRUEDI is here!

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:

Testing the miniRUEDI

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

Slowly but steadily

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