Just be opened in the laboratory of Göteborg, in Sweden, one of the world's largest nuclear magnetic resonance spectrometers. It is essentially constituted by a giant magnet, that allows the realization of studies of macromolecular biology. Its implementation and its functioning need large amounts of liquid helium to Air Liquide Gas AB, a subsidiary of Air Liquide in Sweden, it will supply through a three-year contract.
There is only a dozen of spectrometers at this level in the world. The heart of the device is a huge magnet of 5 metres in height and 10 tons of weight. The magnetic field is generated by high-intensity electric currents in a superconducting material, which offers a negligible resistance to the passage of the current. Superconductivity is achieved due to the extremely low temperatures achieved with liquid helium.
At the time of the launch in March, will be used about 25,000 liters of helium, as well as a large amount of liquid nitrogen to cool the magnet. Once in operation, the device will consume from 10 to 15,000 litres of liquid helium per year.
Commenting on this new contract, Jean-Pierre Duprieu, director of the society and a member of the Executive Committee of Air Liquide, declared: "We are very pleased to provide this pointer laboratory, which demand a very high demands." "This demonstrates the quality of our products and services as well as the competence of our teams".
Helium is extracted from natural gas fields. In liquid state, it has a conductivity excellent, about 30 times higher than the nitrogen.
