Patent ID: 8035388

Claim:
Method for providing a sensitive volume for single-sided NMR, comprising a) generating a first magnetic field at the sensitive volume by at least one first permanent magnet and b) superimposing at least one second magnetic field for homogenizing the first magnetic field in the sensitive volume the at least one second magnetic field being generated by a shimming means for superimposing at least one second magnetic field: wherein the at least one second magnetic field is adjusted to provide a magnetic field homogeneity in the sensitive volume is corresponding to a line width of hydrogen ( 1 H) of less than 10 ppm (parts per million); and wherein the at least one first permanent magnet and the shimming means for superimposing at least one second magnetic field form part of a single-sided NMR apparatus which is constructed and arranged to perform single-sided NMR spectroscopy.
