Abstract:
1. A method of acquiring NMR spectral data from a fluid sample, comprising: placing the fluid sample in an elongated capillary that extends through a magnetic field, including through the center of the magnetic field as enabled by a pair of magnet pole pieces, to provide for a polarized fluid in the capillary; applying a first RF pulse sequence to a first segment of the polarized fluid in the capillary by way of an RF coil configured at the center of the magnetic field and acquiring NMR spectral data from resulting NMR spin precession decay; advancing the polarized fluid in the capillary enough so that a second segment of the polarized fluid that has not been subjected to the first RF pulse sequence moves into the center of the magnetic field; and applying a second RE pulse sequence that is identical to the first pulse sequence to the second segment of the polarized fluid in the capillary by way of the RE coil configured at the center of the magnetic field and acquiring NMR spectral data from NMR spin precession decay, resulting from the second RF pulse sequence.
