Abstract
An MAS stator () for an NMR-MAS probe head () has a bottom bearing () with at least one nozzle and at least one radial bearing (), wherein one substantially circular cylindrical MAS rotor () is provided for receiving a measurement substance. The MAS rotor can be supported by compressed gas in a measurement position within the MAS stator by means of a gas supply device and can be rotated about the cylinder axis of the MAS rotor by means of a pneumatic drive. A suction device () is provided in a space below the radial bearing for suctioning-off the gas introduced by the gas supply device, and generates an underpressure in the space below the radial bearing during measurement operation. This provides a stator for NMR-MAS spectroscopy in which the closure at the head end of the stator is omitted.
