Brief introduction:
90 MB of nuclear magnetic resonance spectrometer, effectively improve the chemical shift resolution, chemical structure information gain, low maintenance cost (without liquid nitrogen, liquid helium), structural analysis can be applied to organic chemistry synthesis detection and scientific research in general. It is mainly used for
Organic chemistry, structural analysis and fine chemical industry field testing. The function:
