  Time Domain NMR FID Experiments(Part I)

  May 21, 2021 Articles / Blog / NMR Principle

  Time Domain NMR FID Experiments(Part I) Introduction The simplest NMR experiment is called an FID (Free Induction Decay) experiment. A single RF pulse (normally a 90 degree pulse) is applied to the sample and the response is measured as a function of time after the RF excitation. Because of its simplicity, the FID application is often used to set up the NMR instrument. In ...

  Benchtop NMR used for the measurement of fluorinated coatings on fibers and textiles

  March 24, 2021 Blog

  Benchtop NMR used for the measurement of fluorinated coatings on fibers and textiles Coated fabric is a fabric or cloth processed by a special process. Mainly based on the cloth, a special process is used to coat a layer of material with special functions, which adds special functions to the cloth. So, it is also called functional coated fabric or cloth. Fluorinated coa ...
