摘要： An adjustment device (1) for an RF resonant circuit (96) of an NMR probe (90) has a plurality of movable elements (6) which are arranged in succession, such that adjacent movable elements mutually engage, so as to be movable relative to one another in a limited range. The movable elements each have at least one electrical functional part (20; 20a-20b) for adjusting the RF resonant circuit. N outwardly oriented electrical contact elements (15; 15a-15b; 23, 24) include at least two functional part terminals (21, 22), and the electrical contact elements are each connected to a functional part terminal. The adjustment device also includes a first connection assembly (11) for slidingly contacting at least a portion of the movable elements from outside, to contact the contact elements in dependence on the movement position of the movable elements, as well as a movement device (4), configured to move one of the movable elements.

摘要： A transport device for transporting an NMR sample to the probe head (16) of an NMR spectrometer by means of a transport system (12) is characterized in that the transport device comprises a shuttle (15) adapted for use with a transport system. The transport system is structured to transport an HR-NMR sample spinner or an NMR MAS rotor (5). The shuttle includes a locking device for the NMR MAS rotor, the locking device being formed such that the NMR MAS rotor is released by unlocking the locking device and can be transferred to and received by the NMR MAS probe head. It is therefore possible to rapidly change from NMR spectroscopy of liquids to NMR spectroscopy of solids, and vice versa, simply by exchanging the probe head, without converting the transport system.

摘要： An NMR probe head has a capacitor with a dielectric (5), which surrounds a cavity (15) in which a capacitor piston (7) is disposed. A sliding bush (9) has a through hole (16) in which a piston operating rod (8) extends. The piston operating rod (8) is connected to a piezo-electric actuator and to the capacitor piston (7) in such a way that it displaces the capacitor piston linearly when a sawtooth voltage is applied to the piezo-electric actuator. The sliding bush thereby applies braking friction to the piston operating rod during linear displacement of the capacitor piston and only allows the piston operating rod to slide through during the steep edges of the sawtooth voltage. This avoids the disadvantages of prior art, wherein the NMR probe head remains compact and the material cost and manufacturing complexity are reduced.
