Rotational exchange gradient imager for in situ magnetic resonance analyses in ultracentrifuge sedimentation of biological materials and rheology investigations |
摘要 |
A detecting method and detector expands the capabilities of Nuclear Magnetic Resonance (NMR) analysis. A Rotational Exchange Gradient Imager (REGI) allows for real-time, in situ investigation of materials subjected to the effects of centrifugal force by NMR analysis. The REGI comprises a cylindrical stator formed of an electrically conductive, non-magnetic material, a rotor contained in the cylindrical stator formed of an electrically non-conductive, non-magnetic material, and a conductor located along a central axis of the cylindrical stator. A sample is contained within the rotor. The stator and central conductor serve to generate the RF magnetic field for NMR analysis. The rotor containing the sample is rotated within a stable air bearing formed between the cylindrical stator and rotor.
