核磁共振光譜儀
Nuclear Magnetic Resonance Spectrometer
Instrument introduction:
Half of the nuclei of isotopes that exist in nature have nuclear spin. These nuclei are like small magnetic needles that rotate around a magnetic field. When the frequency of the external electromagnetic wave is the same as the rotation speed, the energy of the electromagnetic wave is absorbed, which is the phenomenon of "nuclear magnetic resonance (NMR)". The phenomenon of nuclear magnetic resonance was first successfully demonstrated in 1946 by Professors Purcell and Bloch. Nuclear magnetic resonance spectroscopy has become an indispensable instrument in chemistry-related research since the 1970s. Today, in addition to identifying the structure of small chemical molecules, it has become a major technology in biological sciences and medicine, such as structural genome and drug research. There are quite a number of NMRs in China, but currently only Donghua University in the east has a nuclear magnetic resonance spectrometer that can provide analysis and identification of small molecules and biological macromolecules.

Instructions for submitting for testing:
- Please go to the "National Science and Technology Council The Instruments Informantion System" Make an appointment (those who make an appointment, please refer to the relevant regulations to avoid incorrect payment methods).
- Complete the application form on the previous page and send it together with the sample to the Department of Chemistry, National Dong Hwa University. Failure to fill it in completely will affect the pickup time.
- Currently, only liquid samples are tested. The solvent needs to be a solvent containing deuterium (D). The sample weight is about 10~50 mg. Please dissolve it completely until there is no suspended solids.
- Users are required to prepare their own NMR test tubes with a length of not less than 15 cm, no bends, and no damage to the tube mouth. The sample height must be 4~5 cm, and the tube mouth should be closed to avoid contamination and volatilization.
- In order to avoid damaging the insert glass between the instrument coil and the NMR sample tube, please use qualified NMR tubes such as 507, 528 special samples and long-term testing. Please make an appointment in advance.
- If necessary, users can put the sample into a sample bottle and send it to our department. Our department is equipped with test tubes and common solvents, which can be processed on your behalf. The cost of the solvent will be charged. However, if it is a valuable sample, please be responsible for the preparation and recycling by yourself.
- The client shall not use the test results for commercial advertising, evidence in legal proceedings, or other purposes without the consent of the Center. Violators will be prosecuted by the Center in accordance with the law. If the center's reputation is damaged due to the client's improper use of test reports, the center will demand compensation for damages in accordance with the law.
- A first-come-first-served basis is adopted, and the expected response time is two to three weeks.
