| titleOfInvention | A kind of method of obtaining one dimension high resolution NMR spectrogram under non-uniform magnetic field |
| abstract | The invention provides a kind of method of obtaining high resolution NMR spectrogram under non-uniform magnetic field. The method first applies a radio-frequency pulse, and magnetization vector is rotated to XY plane from Z axis, then on both direction, applies phase encoding gradient, in applying the sampling gradient of echo wave plane spectrum image-forming module, gathers NMR signal on third direction. The signal collecting is carried out to data rearrangement row, and the data matrix that permutatation is obtained carries out Fourier transformation, can obtain nmr spectrum corresponding to a series of corpusculum element. Spectrogram corresponding to each corpusculum element is high-resolution. Due to the existence of non-uniform magnetic field, if directly by corpusculum element accumulation projection, the spectra resolution rate obtaining is low. Spectrogram corresponding to corpusculum element carried out to bias correction, then carry out accumulation projection, can obtain high-resolution one-dimensional nuclear magnetic resonance spectrogram. The high-resolution spectrogram obtaining contributes to the chemical analysis in heterogeneous system. |
