ABSTRACT:
An instrument locally measuring mobility of a protic solvent in a sample115based on the gradient magnetic field NMR method has a sample stage116on which the sample115is placed, a magnet113applying a static magnetic field to the sample115, a G coil151and a G coil153applying a gradient magnetic field to the sample115, a small-sized RF coil114smaller in size than the G coil151applying an oscillating magnetic field for excitation and acquiring an NMR signal corresponded to the oscillating magnetic field for excitation and the gradient magnetic field; a pulse control unit108allowing application of the gradient magnetic field and oscillating magnetic field for excitation to be executed according to a predetermined pulse sequence; and an operation unit130calculating the mobility at the specific position of the G coil151, based on information of the NMR signals acquired corresponding to different gradient magnetic fields.
