Abstract

An NMR measurement apparatus is potentially subject to relative motion between the apparatus and a sample. The measurement apparatus includes at least one magnet, at least one coil and circuitry that is coupled to the magnet(s) and coil(s). The circuitry is adapted to use the magnet(s) and coil(s) to perform at least one NMR measurement and indicate the results of the NMR measurement(s). The results are then analyzed to determine an effect of the motion on the measurement(s).
