Dr. Okay's TD-NMR Group
- TD-NMR (Time Domain Nuclear Magnetic Resonance) is a low magnetic field, non-destructive, and quantitative characterization technique used to analyze the physical properties of liquid and semi-solid samples. Unlike Spectroscopic NMR, TD-NMR collects and analyzes signals in the time domain.T1 (longitudinal relaxation): The time it takes to return to the energy level. It is related to the environmental interactions of the molecules.T2 (transverse relaxation): The time of phase loss. It is directly related to the mobility of the molecules and the viscosity of the medium.TD-NMR typically works with T2 measurements because this time provides more direct information about liquid/solid separation and microstructure. It is possible to determine the amounts of components such as oils, water, and protein ratios. It is particularly used in quality control and formulation analysis in industries such as food, pharmaceuticals, polymers, and detergents.
