  Spin Finish Measurement by Low Field NMR

  September 26, 2023 Applications / Articles / Food & Agriculture / NMR Principle

  Oil applied to fibers serves multiple essential purposes, primarily functioning as a lubricant and an antistatic agent. Additionally, it plays a crucial role as a carrier for various chemical agents, including fiber bactericides, flame retardants, and colorants. The spin finish of fibers stands out as a pivotal quality control parameter that directly determines the fiber's ...

  Pulsed NMR of NIUMAG

  September 19, 2023 Applications / Articles / NMR Principle

  Pulsed NMR relies on the interaction between atomic nuclei with magnetic moments (such as hydrogen nuclei or protons) and an external magnetic field. When a sample is placed in a strong magnetic field, the nuclei align with the field. The application of a radiofrequency pulse at a specific frequency causes nuclei to flip from their aligned state to a perpendicular orientati ...

  Low Field NMR Analysis for Investigating Rubber Crosslinking

  September 12, 2023 Applications / Articles / NMR Principle

  Low-field NMR analysis technology employs pulses to excite hydrogen protons within material samples, causing them to resonate. Subsequently, after the pulse ceases, hydrogen protons undergo relaxation, with varying relaxation times for hydrogen protons in different states within the sample. The analysis of relaxation signals enables the direct or indirect assessment of mate ...

  Benchtop NMR Analysis for Fibers and Textiles

  September 8, 2023 Applications / NMR Principle

  The benchtop NMR analysis technique revolves around the direct measurement of the nuclear magnetic resonance (NMR) signal of fluorine-19. As the fluorine content correlates directly with the intensity of the detected NMR fluorine signal, the fluorine content (expressed as wt%) can be deduced using an appropriate calibration curve.
