Abstract
A method is provided for acquiring multiple NMR response signal data in rapid succession for averaging NMR spectral data from a sample. The fluid sample is placed in a capillary that extends through the magnetic field of the NMR spectrometer, including through the center of the magnetic field to place a segment of the sample in the magnetic center. After the sample fluid, initially magnetized by the magnetic field, is activated to emit an NMR pulse signal, the fluid in the capillary is advanced rapidly to put another pre-magnetized segment of the sample fluid in the fluid center, acquiring an NRM pulse signal, and continuing the cycle until a desired number of NMR response data signals from the sample have been acquired. Those response data from multiple acquisitions are then averaged.
