Abstract
An NMR spectroscopy method monitors a component of a sample, the component having two resonances in coupled together different spectral regions. The first resonance lies in a region including a resonance of a second component of a sample while the second resonance lies in a spectral region including a resonance of a third component of the sample. Two spin-echo pulse sequences each consisting of pulses of a predetermined frequency are applied, the spin-echo resonance spectra together being used to obtain the second resonance of the first component with the resonance of the third component suppressed.
Claims8
An NMR spectroscopy method for monitoring a component of a sample, the component having at least two coupled resonances in different spectral regions, the first resonance lying in a first spectral region including a resonance of a second component of the sample, and the second resonance lying in a second spectral region including a resonance of a third component of the sample, comprising:
- applying two spin-echo pulse sequences consisting of pulses of a predetermined frequency, the sequences each being effective to produce a suppressed resonance signal in the first spectral region, in one of the sequences the echo pulse not exciting the first resonance, and in the other of the sequences the echo pulse exciting the first resonance;
- recording a spin-echo spectrum produced by each of the sequences;
- and using the two recorded spin-echo spectra together to determine the second resonance of the first component with the resonance of the third component suppressed.
