Nmr-Nuclear Magnetic Resonance Instruments (RAY-NMR100)

NMR Analyzer
Based on high-performance spectrometer NmdigI and two-box design, RAY-NMR100 NMR Analyzer was launched in 2008. Being widely used in food, agriculture, biomedical, petrochemical, chemical fiber, polymer, and building material, etc. by virtue of its high accuracy, good repeatability, and high stability, it meets the demands of both quality control & assurance and R&D work in the above fields. Besides, NMR method has many advantages such as being fast, easy to use, green and pollution-free, harmless to people and environment, minimal sample preparation and chemical reagent, non-destructive.
