PROBE, DEVICE AND METHOD FOR NUCLEAR MAGNETIC RESONANCE ANALYSIS WITH MAGIC-ANGLE SPINNING

摘要

An NMR analysis device comprising an NMR analysis probe and a cryostat linked by a cryogenic line, the probe a frame, a sample-holder having a rotor, suitable for receiving a sample of material to be analysed, a bearing for rotationally guiding the sample-holder relative to the frame, a compression module and a cryorefrigerator arranged in the cryostat, upstream of the compression module, and a first element for channelling a third gaseous flow of fluid to a turbine and a second element for channelling a second gaseous flow of fluid to the bearing, the bearing being of aerostatic or aerodynamic type.
