The JEOL JNM-1 is a nuclear magnetic resonance (NMR) system, the first such instrument released in Japan. JEOL released the JNM-1 in 1956.[1]
The JEOL JNM-1 is a nuclear magnetic resonance system. The JEOL JNM-1 was released in 1956. The JEOL JNM-1 was the first NMR system in Japan.[1]
A nuclear magnetic resonance system places a sample in a strong magnetic field and excites selected nuclei with radiofrequency energy. A nuclear magnetic resonance system detects the resulting response from the nuclei and converts that response into spectra for analysis. Nuclear magnetic resonance systems generally combine a magnet, radiofrequency transmission and reception hardware, sample handling, and control software.
A nuclear magnetic resonance system is generally used in analytical laboratories rather than on the main wafer processing line. Nuclear magnetic resonance systems are typically used after sample collection or preparation steps and before interpretation, reporting, or subsequent materials decisions. Nuclear magnetic resonance systems support characterization workflows for chemicals, materials, and research samples.
Nuclear magnetic resonance systems are used for molecular identification, structural analysis, and purity assessment. Nuclear magnetic resonance systems are also used to study reaction products, solvents, polymers, and other research or production related materials. In industrial and research settings, nuclear magnetic resonance systems help characterize samples whose composition or bonding environment must be understood.
Released in 1956 as the first NMR system in Japan.
