| Abstract: | Electron Paramagnetic Resonance (EPR) is the only spectral method for direct detection of paramagnetic substances. EPR technology can be used for the qualitative and quantitative analysis of free radicals and transition metals in solid, liquid, gas, cell and living samples. It is widely used in chemistry, material science, life science, quantum physics and other researches. This report discusses the basic principle, instrument structure, common problem solving, daily maintenance, and management model of the electron paramagnetic resonance spectrometer (German Bruker A-200) in the State Key Laboratory of Natural and Biomimetic Drugs of Peking University Health Science Center, so that the instrument can be fully used for various scientific researches. |
