Abstract
Apparatus for Nuclear Quadrupole Resonance testing a remote sample containing a given species of quadrupolar nucleus includes at least one probe (112) having a given maximum cross-sectional dimension; a device (102) for applying excitation to the probe or at least one of the probes to excite nuclear quadruple resonance for a selected range of distance of the sample from each such probe, the selected range being at least one tenth of the given maximum dimension of the probe, the apparatus being adapted to produce a non-uniform field over the selected range; and a device (106) for detecting the resonance response signal from the sample via the probe or at least one of the probes; the excitation being such as would generate non-zero resonance signals at all distances within the selected range.
