PROBE FOR NUCLEAR MAGNETIC RESONANCE

PROBLEM TO BE SOLVED: To prevent reduction in resolution of a nuclear magnetic resonance spectrum system by adjusting the susceptibility of a bobbin being the constitutional components of the RF coil for making equal to that of atmosphere. SOLUTION: The preform of bobbin 1 is constituted with e.g. quartz glass, and a metallic foil film 3, the susceptibility of which is inverted with plus and minus sign of the preform e.g. chromium (Cr) is stuck thereon. The total susceptibility per unit volume (SI unit system) of the preform and the metallic foil are made equal to the susceptibility (SI unit system) of the atmospheric matter. Thereby, the generation of erroneous magnetic field from the contact part between the bobbin 1 of the RF coil 2 is inhibited and the degradation of resolution of detection coil for detecting the nuclear magnetic resonance spectrum is prevented.
