Abstract
This invention concerns a new embodiment of the instrument to measure nuclear polarization described in U.S. Pat. No. 6,356,080.The coil, that couples the nuclear polarized substance to the electronics, has been designed not to pick up ambient electromagnetic noise. The output from the low level oscillator is passed through a Schmidt trigger to reduce noise. A local oscillator beats with the output of the low level oscillator to provide an audible output.The instrument is automated, using a microprocessor with a customized downloaded program, to control the operation of the instrument and to output the results of measurement to a liquid crystal display and, if desired, to an external computer. This computer is not necessary and the instrument can act as a stand alone.
