ABSTRACT:
A method for filtering spurious resonances from an NMR dataset comprises the steps of:(a) creating a first, non-oscillating magnetic field of a predetermined field strength across a sample,(b) intermittently exposing the sample to a second, oscillating magnetic field orthogonal to the first to generate an NMR signal,(c) detecting the NMR signal from the sample,(d) adjusting the first magnetic field to a different predetermined field strength and repeating steps (a) to (c), and(d) comparing the detected signals to obtain an NMR dataset from the sample from which spurious resonances have been filtered.
