Josef Dadok National NMR Centre installed a nitrogen liquification unit for its 850 MHz NMR spectrometer

28 Aug 2020

The liquification unit called BSNL (Bruker Smart Nitrogen Liquefier) uses an excess cooling capacity of the cryogenic probe system to liquify and recycle the nitrogen evaporating from the magnet. The nitrogen refill interval is thus extended from 2-3 weeks to more than 6 months. The equipment increases the user comfort and reduces the maintenance time and cost. Long measurements do not need to be interrupted to refill nitrogen anymore. At the same time, the liquid nitrogen consumption is greatly reduced. By the end of the year, similar units will be installed at all spectrometers in the Centre equipped by cryoprobes, namely 950 MHz , 600 MHz, and 700 MHz instruments. The unit was purchased using finances from the European Regional Development Fund-Project „CIISB4HEALTH“ (No. CZ.02.1.01/0.0/0.0/16_013/0001776).
