Provided is a compact flow-through NMR analyzer with high NMR signal detection sensitivity. The flow-through NMR analyzer comprises: a solution feeding tube (18) for circulating a sample fed by a solution feeding pump (6); a superconducting magnet (7) that surrounds a sample housing space, which is surrounded by the side walls of the solution feeding tube (18), around the axis of the solution feeding tube (18), in such a manner that a static magnetic field is produced along the axis of the solution feeding tube (18); a vacuum container (12) that houses the superconducting magnet (7) in a chilled state, and surrounds a housing space around the axis of the solution feeding tube (18); and an RF coil (22) for providing high-frequency electromagnetic waves to a sample inside the housing space, and for detecting the NMR signal from said sample. The RF coil (22) is within a region of the solution feeding tube (18) that is enclosed by the superconducting magnet (7) and a magnetic field correction coil (4c), and is integrally formed with the side walls of the solution feeding tube (18). |
