Abstract
An NMR method and apparatus uses a magic angle spinning (MAS) system with a MAS turbine having a MAS stator and a MAS rotor. At least two different gases or gas mixtures are fed to the stator through separate gas feeds, a first for the driving of the rotor and another, which is different from the first, for the bearing of the rotor. Respective pressures of the at least two different gases or gas mixtures are regulated separately, and the different gases or gas mixtures are prevented from mixing in the stator by means of a flushing seal through which they at least partially flow out of the stator. Conventional outflow nozzles do not need to be adapted, and the rotor can be operated at a high rotational frequency even at low pressures. The pressures remain stable so that no rotational oscillations occur during the NMR measurement.
