Abstract: An instrument locally measuring mobility of a protic solvent in a sample 115 based on the gradient magnetic field NMR method has a sample stage 116 on which the sample 115 is placed, a magnet 113 applying a static magnetic field to the sample 115, a G coil 151 and a G coil 153 applying a gradient magnetic field to the sample 115, a small-sized RF coil 114 smaller in size than the G coil 151 applying 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 unit 108 allowing application of the gradient magnetic field and oscillating magnetic field for excitation to be executed according to a predetermined pulse sequence; and an operation unit 130 calculating the mobility at the specific position of the G coil 151, based on information of the NMR signals acquired corresponding to different gradient magnetic fields.

Abstract: Excitation-use high frequency RF generated by an RF oscillator is modulated by a modulator based on control by a pulse control unit, to give a pulse form. The generated RF pulse is then amplified by an RF amplifier, and set to a small-sized RF coil. The small-sized RF coil applies the RF pulse to a specific position of a sample placed on a sample stage, and detects echo signals of the RF pulse. The echo signal is amplified by a preamplifier, and is then sent to a phase detector. The phase detector detects the echo signal, and sent it via an A/D converter to an operation unit. The operation unit calculates T2 relaxation time constant based on intensity of the echo signal, and the water content at the predetermined position of the sample is calculated based on the calculated T2 relaxation time constant.

Abstract: Excitation-use high frequency RF generated by an RF oscillator 102 is modulated by a modulator 104 based on control by a pulse control unit 108, to give a pulse form. The generated RF pulse is then amplified by an RF amplifier 106, and set to a small-sized RF coil 114. The small-sized RF coil 114 applies the RF pulse to a specific position of a sample placed on a sample stage 116, and detects echo signals of the RF pulse. The echo signal is amplified by a preamplifier 112, and is then sent to a phase detector 110. The phase detector 110 detects the echo signal, and sent it via an A/D converter 118 to an operation unit 130. The operation unit 130 calculates T2 relaxation time constant based on intensity of the echo signal, and the water content at the predetermined position of the sample is calculated based on the calculated T2 relaxation time constant.
