  Pulsed NMR Field Shimming Current

  September 23, 2022 Applications / Articles / NMR Principle

  Pulsed NMR Field Shimming Current In the pulsed NMR system, the sample to be tested needs to be placed in a uniform static magnetic field, so that the proton magnetic moment in the water molecules in the sample tends to one direction, and the detection area is irradiated by radio frequency signals that can be absorbed by protons, and by applying radio frequency sequenc ...

  Low-field NMR Method for the Detection of Oil Content in Wool Fibers

  August 29, 2022 Applications / Articles / NMR Principle

  Low-field NMR Method for the Detection of Oil Content in Wool Fibers Why Measure Oil Content of wool fibers? Oil on the fiber is usually used as a lubricant or an antistatic agent, it is also used as a carrier for chemical agents such as fiber bactericides, flame retardants, and colorants. The oil content is also an important quality control parameter, which directly deci ...

  August 16, 2022 Articles / Benchtop NMR / More NMR MRI / NMR Principle

  The development history of Time domain NMR(MRI) technology NMR is a physical phenomenon. As early as 1945, the Purcell and Bloch groups independently discovered the NMR phenomenon. As an analytical method, it is widely used in the fields of physics and chemistry to study the molecular structure of substances. The Time domain NMR technology and later NMR imaging proposed in ...

  Agglomeration State of Particles Study by Low Field NMR

  August 11, 2022 Articles / Blog / NMR Principle

  Refers to the attachment of primary particle clusters or small particles to large particles connected by points and corners, and its total surface area is larger than that of agglomerates, but smaller than the sum of the individual particles, and redispersion is relatively easy. Agglomerates and agglomerates are also called secondary particles.
