  • Apparatus and method for compensation of magnetic susceptibility variation in NMR microspectroscopy detection microcoils
    Patent number: 5684401
    Abstract: An apparatus and method for compensation of magnetic susceptibility variation in NMR microspectroscopy detection microcoils. NMR detection microcoils are formed with side-by-side windings in order to approximate a uniform cylindrical sheet coil. The wire may have a thin layer of insulation in order to prevent shorting between adjacent turns, or (if the wire diameter is small enough) uninsulated wire may be wound with the adjacent turns touching without fear of shorting between coil turns. Additionally, a susceptibility matching medium, such as a perfluorinated hydrocarbon, may be placed around the microcoil to minimize susceptibility-induced variations in the B.sub.0 magnetic field.
