Nuclear Magnetic Resonance Spectrometer NMR 800MHz
（Bruker BopSpin Inc., AVANCE Ⅲ）
The NMR 800MHz instrument has a superconducting magnet with a magnetic field intensity of 18.8 tesla, which corresponds to a proton (1H) resonance frequency of 800MHz. The unit is connected with a cryogenic sensitive detector that can detect 1H, 15N and 13C. This detector has high accuracy with reduced thermal noise, achieved by cooling the detector and increasing the ratio of signal to noise by four or five times.
Features:
Increased magnetic intensity increases the sensitivity of NMR signals and resolution. This unit is capable of measuring trace amounts of specimen, something that was not possible using conventional spectrometers, and of obtaining detailed information on specimens with a complex molecular structure. This unit is useful for understanding the structures and properties of polymer functional materials, as well as 3D structures and the function of biomolecules such as proteins.
Nuclear Magnetic Resonance Spectrometer NMR 400MHz
（Bruker BopSpin Inc., AVANCE Ⅲ）
The 
NMR 400MHz instrument has a superconducting magnet with a magnetic field intensity that corresponds to a proton (1H) resonance frequency of 400MHz, which is suitable for one- or two-dimensional measurement for 1H and multinuclear materials. It is possible to measure multiple samples consecutively by using an automatic sampler and exclusive software. An NMR spectrum of specimens isolated from natural materials and compound specimens can be measured and analyzed, which in turn enables analysis of the structure of new materials and confirmation of synthetic reactions.
Features:
This spectrometer is suitable for measurement of extracted or synthesized low-molecular weight compounds. Since most of the operation is automated, it is easy for beginners to measure an NMR spectrum. When the resolution of the NMR spectrum obtained by NMR 400MHz is insufficient, the use of NMR 800MHz, which has a higher magnetic field, is recommended.
