COMPLETE-FLOW-THROUGH-TYPE NMR MEASURING METHOD AND DEVICE FOR FLOW-THROUGH-TYPE REACTOR

摘要

PROBLEM TO BE SOLVED: To provide a complete-flow-through-type pulse FT-NMR measuring method and a device for the same capable of observing a changing state or a state at a specific point in time in the progress of reaction as a state at a specific moment instead of average observation by NMR.;SOLUTION: Samples to be measured S1 and S2 continuously supplied from a sample supplying system are supplied at any given supplying speed for a flow reaction tube 2 arranged in an external magnetic field. The samples in the flow reaction tube in the external magnetic field are irradiated with pulses including a frequency range for observation at desired intervals. Signals of wavelengths in the range of frequencies radiated at every irradiation with the pulses are superposed (integrated or added) by a plurality of times at the radiating intervals from the samples. The superposed signals are used as observation signals for the samples in the complete-flow-through-type NMR measuring method and the complete-flow-through-type NMR measuring device for the same.;COPYRIGHT: (C)2002,JPO
