In industrial production and research laboratories, a fast, effective, simple, and practical method is needed to evaluate crosslinking density. Low-field NMR is ideal for detecting changes in crosslinking density during production. The NMR method is simple and easy to use, making it a valuable tool for quality control in the polymer production process.

Low-field nuclear magnetic resonance primarily refers to nuclear magnetic resonance instruments with relatively low magnetic field strength. The application fields of low-field NMR technology are very broad and are continuously expanding.

Small NMR (desktop NMR) provides comprehensive research solutions and is suitable for a wide range of materials, including elastomers such as rubber, as well as membrane materials and nanomaterials in the biological field.
