20220050157 · 2022-02-17 · ·

A magnetic resonance measurement apparatus according to the present invention includes a first LC circuit that forms an oscillating magnetic field that causes an object to exhibit magnetic resonance. The first LC circuit includes a parallel connection assembly including a diode. The parallel connection assembly further includes a diode connected, in parallel and in reverse direction, to the diode, or an inductor connected in parallel to the diode. In a first state in which oscillating voltage for forming the oscillating magnetic field is applied to the first LC circuit, the diode of the parallel connection assembly functions as a short-circuit such that the resonance frequency of the first LC circuit becomes a first resonance frequency. In a second state in which oscillating voltage is not applied to the first LC circuit, the diode of the parallel connection assembly functions as capacitance such that the resonance frequency of the first LC circuit becomes a second resonance frequency that is different from the first resonance frequency.

NMR-MAS probe head with integrated transport conduit for an MAS rotor

An NMR MAS probe head (1) has an MAS stator (7) with a base bearing (8) and a front bearing (75) for receiving a substance to be measured at a measurement position within an MAS rotor. The front bearing has an opening for inserting the MAS rotor into the space between the base bearing and the front bearing.
