NMR Principle
What is NMR? Nuclear magnetic resonance (NMR) is a physical process in which the spin level of an atomic nucleus with a non-zero magnetic moment undergoes Zeeman splitting under the action of an external magnetic field, and resonance absorbs a certain frequency of radio frequency radiation. This process is called nuclear magnetic resonance. NMR instruments have become rout ...

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 ...

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 ...

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 ...
