ABSTRACT:
A high speed cylindrical nuclear magnetic resonance (NMR) sample spinner includes a housing to which pressurized air is supplied. A cylindrical stator is mounted within the housing and is adapted to support a receiver coil. There are spaced along the length of the stator a number of circumferentially spaced openings through which the pressurized air is transmitted from the housing to the interior of the stator. A solid to be analyzed by nuclear magnetic resonance is placed within a rotor and the rotor is inserted into the stator. The rotor is supported within the stator by the pressurized air transmitted through one or more of the openings formed in the stator. The rotor is driven by a turbine-shaped end cap which is responsive to the air supplied through other of the openings formed in the stator.
