Title:
磁気共鳴法を用いて試料中のプロトン性溶媒の挙動を局所的に測定する測定装置、測定方法、プログラム
Document Type and Number:
Japanese Patent JP5469689
Kind Code:
B2
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 alloing 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.
