Claim Text:
1. A flow-through Nuclear Magnetic Resonance (NMR analyzer for detecting an NMR signal of a sample fed from a solution feeding pump, the flow-through NMR analyzer comprising: a solution feeding pipe for flowing the sample fed from the solution feeding pump; a superconducting magnet that encloses a housing space, which is surrounded by a side wall of the solution feeding pipe, around an axis of the solution feeding pipe such that a static magnetic field is generated along the axis of the solution feeding pipe; a housing container which houses the superconducting magnet in a cooled state and which encloses the housing space around the axis of the solution feeding pipe; a magnetic field correcting coil which encloses the housing space around the axis of the solution feeding pipe between the housing container and the solution feeding pipe and which corrects homogeneity of a magnetic field in the housing space; and a detecting coil which applies high-frequency electromagnetic waves to the sample inside the housing space and which detects the NMR signal from the sample, wherein the detecting coil is integrally formed with the side wall of the solution feeding pipe in a region of the solution feeding pipe that is enclosed by the superconducting magnet and the magnetic field correcting coil, and the detecting coil is embedded in the side wall of the solution feeding pipe.
