| 20090128147 | NUCLEAR MAGNETIC RESONANCE SPECTROSCOPY WITH MULTIPLE-COIL PROBES - An NMR inspection apparatus comprises a system for providing a dissolved, hyperpolarized sample and an NMR analysis system connected to the hyperpolarizing system are disclosed. The NMR analysis system includes a magnet for generating a substantially homogeneous magnetic field in a working volume suitable for carrying out NMR and a number of RF magnetic field generators located in the working volume. A non-electrically conducting conduit passes adjacent the RF magnetic field generators and is coupled to the hyperpolarizing system so as to convey a hyperpolarized sample past each RF magnetic field generator in sequence. A sample control system controls movement of a sample through the conduit. An NMR signal acquisition system controls the RF magnetic field generators to generate RF magnetic fields in accordance with a predetermined pulse sequence and detects the resulting NMR signals from the portions of the sample exposed to the RF magnetic fields. | 05-21-2009 |
