摘要： PROBLEM TO BE SOLVED: To provide a nuclear magnetic resonance probe reducing loss by high-frequency cable from a probe coil to a preamplifier and enhancing sensitivity of an NMR signal.
SOLUTION: A changing-over switch 1 for the NMR probe is divided into a switching section 20 including a switching device 14 and a filtering section 19 filtering the switch control signal and the RF transmitted signal. The switching section 20 is arranged within a probe body 21 inserted into a magnet of the probe. The filtering section 19 is arranged near a measuring device 4 exterior of the probe. The switching section 20 reduces the cross sectional structure of thickness and breadth corresponding to elongated shape of a probe body 21. Thus, the length from a probe coil to a preamplifier can be shortened substantially to reduce the loss.

摘要： PROBLEM TO BE SOLVED: To provide an NMR probe and an NMR apparatus which can correct an error magnetic field easily without upsizing a room-temperature shim coil or a cooling structure. SOLUTION: The NMR probe includes an antenna coil and a probe housing formed with a hole for inserting a sample and is inserted into uniform magnetic field space. The probe housing includes a passive magnetic field correction means which does not feed a current. The passive magnetic field correction means is achieved by, for example, piercing the probe housing, adding a paramagnetic material or ferromagnetic material to the probe housing, or adding a member of the same material as the housing material to the probe housing. By providing the probe itself, which can be an error magnetic field factor, with a magnetic field correction function, a shim coil which is upsized or feeds a large current is not required to be specially installed, allowing to correct the error magnetic field by the probe easily and with space saved.
