LADP-2 Experimental System o Pulsed NMR
Pulsed Fourier fesuiaʻi le malosiaga faʻanatinati faʻanatinati faʻaaogaina le pulsed RF fanua e galue i luga o le malosiʻaga faaniukilia e maitauina le tali atu o le malosiʻaga faaniukilia i le uaua, ma faʻaaogaina vave Fourier fesuiaʻi (FFT) tekonolosi e suia ai le taimi faʻailoga faailo i taimi masani faailo, o le e tutusa ma le tele o taimi tasi faifai pea galu faaniukilia resonance spectrometers e fiafia i le taimi e tasi, o lea o le faaniukilia resonance maneta gaioiga mafai ona maitauina i se tele lautele, ma o le faailo e mausali I le taimi nei, uaua auala o loʻo faʻaaogaina i le tele o NMR spectrometers, aʻo uaua auala e faʻaaogaina i le MRI.
Faʻataʻitaʻiga
1. Malamalama i le autu faʻavae tino ma faʻataʻitaʻiga faʻataʻitaʻiga o se PNMR faiga. Aʻoaʻo e faʻamatala fesoʻotaʻi faʻafitauli tino i PNMR faʻaaogaina o vasega masani ata faʻatusa.
2. Aʻoaʻo e faʻaaoga faʻailo o le echo spin (SE) ma le pala fua faʻatosina (FID) e fua ai T2(taimi malolo faʻataʻamilo) Iloilo le aafiaga o le maneta o le homogeneity i luga o le NMR faailo.
3. Aʻo e fua T1 (spin-lattice relaxation time) faʻaaoga le toe faʻaleleia.
4. Malamalama agavaʻa i le faʻamalologa auala, mataʻituina le aʻafiaga o paramagnetic ions i taimi o le faʻaaluina o le eletise.
5. Fua T2o le kopa sulfate solution i vaega eseese. Fuafua le va fealoaʻi o T2 ma le suia o le mafaufau loloto.
6. Fua le faʻafesuiaʻiga o vailaʻau i le vailaʻau.
