RelaTE
Time-Domain Nuclear Magnetic Resonance (TD-NMR)
Relaxation Spectrum Analysis Software
For the relaxation curve data M(t) obtained using the Bruker minispec mq20 time-domain nuclear magnetic resonance (TD-NMR) instrument,
Fit the superposition of Lorentz, Gauss, or Weibull-type exponential functions given by the relaxation time T2j,
This software is for calculating the relaxation spectrum Fj (superposition coefficient).
About the SoftwareAbout Software
01Problems with Conventional Methods
The analysis is highly arbitrary (number of components, Weibull parameters)
Comparing multi-component systems is difficult
02Analysis using RelaTE (n: approximately 100–200)
Analysis Using Spin-Spin Relaxation Spectra
Information obtained
Crosslinking degree of polymers, network chain concentration, amount of additives, degree of degradation, plasticity, stress state, etc.
Information on molecular mobility and structural heterogeneity (particularly useful in structural analysis of rubber materials)
Examples of Application Fields
Material Classification：Design of new polymer materials and process optimization
Food sector：Evaluation of food quality and safety
Pharmaceutical field：Investigation of the crystallinity, solubility characteristics, and stability of pharmaceuticals
Petroleum and Science：Evaluate the fluidity, moisture content, viscosity, and diffusion behavior of liquids containing chemicals in petrochemical products and chemical processes.
Medical Field：Investigate the tissue properties of biological tissues and substances within the body, the nature of tumors, and the absorption, distribution, metabolism, and excretion (ADME) characteristics of pharmaceuticals.
