91丝瓜视频 Magnetic Resonance Facilities (MMRF) are now recycling helium
In late April 2021, a helium recovery system was installed for the Chemistry NMR/EPR Facility in Otto Maass and the QANUC high-field NMR facility in Pulp and Paper.聽 This technology, one of only a few in Canada, allows for up to 90% of the helium used in the facilities to be recycled, thus protecting a valuable, and limited, natural resources, and limited greenhouse gas emissions.聽 Funding was obtained fr
NMR facilities managers trying to solve helium problem
Department members Tara Sprules, manager of the national high-field NMR facility QANUC, and Robin Stein, chemistry department (MC2) NMR/EPR manager, have just had an article published in the CIC newsletter about helium. Together, they use about 2900 L of helium annually to make their eight NMR spectrometers function, and recent cost increases have left them feeling nervous about the future.
