PROBLEM TO BE SOLVED: To provide a graftable nuclear magnetic resonance spectrometer for measuring chemical composition of fluid and/or flow velocity of the fluid. SOLUTION: This graftable nuclear magnetic resonance spectrometer is stored in a housing, and has an array of permanent magnets 1, 2, 3 and 4 for generating a homogeneous static magnetic field with an adequate intensity for analyzing a fluid sample flowing in a catheter 6 crossing the graftable spectrometer. The graftable spectrometer comprises an array of electronic circuits 8 and 9 for exciting and detecting nuclear magnetic resonance signals and at least one excitation coil 7 for collecting nuclear magnetic resonance signals returning with exposing the fluid sample to an exciting signal. The spectrometer includes an RF circuit and an antenna 10 required for communicating with a guidedly connected reading device in a conventional remote measuring method. |
