  Low field NMR

  January 3, 2023 Applications / Articles / NMR Principle / Products

  The magnet of the low field NMR experiment instrument is mainly realized by using the micron precision machining technology, therefore, its magnetic field uniformity is relatively high under normal circumstances. At the same time, the pulse MRI experiment instrument uses a thermostatic controller to control the magnet, so its stability is relatively high. In addition, with ...

  Spin Finish Measurement by NMR

  December 13, 2022 Applications / Articles / NMR Principle

  The traditional extraction method takes 5-6 hours for one measurement, while chemical fiber production is continuous and high-speed production, and problems cannot be controlled in time. At the same time, this method is costly and consumes a lot of reagents and labor. The NMR method has the advantages of fast, non-destructive, green, and does not consume chemical reagents. ...

  Pulsed NMR

  November 11, 2022 Applications / Articles / NMR Principle

  The pulsed NMR experiment instrument is composed of few parts, mainly including magnet, probe, switching amplifier and phase detector. The inside of the probe includes a gradient coil and a radio frequency coil mainly. The gradient coil inside the probe can recognize spatial phase encoding and frequency encoding, while the radio frequency coil inside the probe mainly puts t ...

  Time Domain NMR (TD-NMR)

  October 25, 2022 Applications / Articles / NMR Principle

  Time-domain NMR (TD-NMR) is a NMR technique based on relaxation time detection. Time-domain NMR is generally tested and analyzed through T1 and T2 relaxation times. It is a characterization method, and the testing process is fast and non-destructive.

  Low Field NMR Study on Colloid Swelling Process

  October 18, 2022 Applications / Articles / NMR Principle

  Low-field nuclear magnetic resonance (Low Field NMR) has great potential to study water transport and micro-structure of water mobility-based polymer networks. Unlike high-resolution NMR, low-field NMR (Low Field NMR) is mainly used to indicate structural heterogeneity and molecular mobility of interactions by measuring relaxation times. Studies have shown that low-field nu ...

  Benchtop NMR Measurement of Fluorinated Coatings on Fibers and Textiles

  October 11, 2022 Articles / Benchtop NMR / NMR Principle

  Fluorinated coatings are commonly used in fibers and textiles to provide oil resistance, water resistance, ease of cleaning and flame retardant properties. Can be used in carpets, outdoor products, and performance apparel. The control of the amount of fluorinated coating is very critical. Controlling the content of fluorinated coating can optimize the process and improve th ...
