A spectrometer is a high-performance scientific instrument used to observe nuclear spin resonance phenomena, which analyzes the molecular structure of a substance at the atomic level by placing a sample (atomic nucleus) in a strong magnetic field. Nuclear magnetic resonance spectrometer plays an important role in the analysis of organic compounds, polymer materials, natural products and polymers, as well as biological metabolites, and is widely used in fields such as chemical engineering, biology, materials science, drug development, food safety, and preclinical research.
