China Wholesale Double beam infrared spectrometer Quotes – LADP-2 Experimental System of Pulsed NMR – Labor
China Wholesale Double beam infrared spectrometer Quotes – LADP-2 Experimental System of Pulsed NMR – Labor Detail:
Pulsed Fourier transform nuclear magnetic resonance uses pulsed RF field to act on the nuclear system to observe the response of the nuclear system to the pulse, and uses fast Fourier transform (FFT) technology to transform the time domain signal into frequency domain signal, which is equivalent to multiple single frequency continuous wave nuclear magnetic resonance spectrometers are excited at the same time, so the nuclear magnetic resonance phenomenon can be observed in a large range, and the signal is stable At present, pulse method is used in most NMR spectrometers, while pulse method is used in MRI.
Experiments
1. Understand the basic physical theory and experimental configuration of a PNMR system. Learn to explain related physical phenomena in PNMR using classical vector model.
2. Learn to use signals of spin echo (SE) and free induction decay (FID) to measure T2 (spin-spin relaxation time). Analyze the influence of magnetic field homogeneity on NMR signal.
3. Learn to measure T1 (spin-lattice relaxation time) using reverse recovery.
4. Qualitatively understand the relaxation mechanism, observe the effect of paramagnetic ions on nuclear relaxation time.
5. Measure T2 of copper sulfate solution at different concentrations. Determine the relationship of T2 with the change of concentration.
6. Measure the relative chemical displacement of the sample.
