WebApr 12, 2024 · The specific identification of the oil and moisture signals of soybean seeds using longitudinal relaxation time (T1) and transverse relaxation time (T2) successfully solved the problems of less mobile water, overlapping free water, and oil signals. Therefore, LF-2D-NMR can complement conventional LF-NMR assays, and this study provides a new ... WebAn alternative to T1-T2 vs. diffusion is T1 vs. T2. The contrast between T1 and T2 relaxation times increases at short T2 times, enabling differentiation of poro-fluid types. A continous measurement of T1-T2 coulpled with a short echo spacing, high vertical resolution, and tolerance to low porosity and high salinity

WebTo set up a T1 experiment, start with recording a normal proton spectrum to adjust the spectral sweep width SWH, acquisition time aq and other parameter if necessary. 2) Create new dataset and load “ Proton_T1” parameter set. Update the parameters with the ones you obtained from last step. The recycle delay D1 should be ~2-5*T1. Adjust NS WebApr 2, 2024 · T2* decay refers to an exponential decrease in M xy (i.e. signal strength) following the initial excitation pulse as a function of time constant T2*. A picture of the signal or free induction decay (FID) is shown on the right, occurring immediately after a 90 o RF excitation pulse in a liquid phantom .
