The 700 MHz spectrometer must be filled by an amount of ~560 liters of liquid helium per year, the 600 MHz needs ~320 liters/year to maintain the magnet at supraconductivity temperatures. This represents a consumption of >600 m3 of helium gas.
In October 2018, a helium recovery system has been installed beside the NMR platform in order to preserve the helium gas resource and to allow recycling of the gas into liquid helium produced by the Strasbourg University Helium Production facility – F. Hopfner.
This project was sponsored by FRISBI.
The system was provided by Girodin-Sauer and was installed by the IGBMC technical services – C.Kolb, C. Untereiner, C.Vatté, T. Zill, R. Von Scheidt, with the kind support of F. Hopfner, C. Ling.
