Abstract
Imaging apparatus are used in a toroid cavity detector for nuclear magnetic resonance (NMR) analysis to hold samples relative to a principal detector element which is a flat metal conductor, the plane of which is parallel to the longitudinal axis of the toroid cavity. A sample is held adjacent to or in contact with the principal detector element so that the sample can be subjected to NMR analysis when a static main homogeneous magnetic field (B0) produced by a NMR magnetic device is applied to the toroid cavity and an RF excitation signal pulse is supplied from a potentiostat to the principal detector element so that an alternately energized and de-energized magnetic field (B1) is produced in the sample and through the toroid cavity. The sample may be components of a coin cell battery which are mounted within the toroid cavity relative to the principal detector element by an non-conductive coin cell battery imager or a press assembly so that the components are hermetically sealed together and so that a direct current potential can be applied to the components. Alternately, a sample is positioned within an O-ring maintained relative to the principal detector element by a pair of gla…
