Experimental analysis instruments can be divided into pre-processing equipment and analysis and testing equipment according to the analysis process. The upstream of the experimental analytical instrument industry chain is mainly composed of sample introduction systems, ion sources, analyzers, detectors, etc.; the downstream applications are extensive, and with the accelerated innovation of analytical technologies in various disciplines such as physics, chemistry, optics, and life sciences, it has been widely used. It is used in life science, medical health, new material research, new energy, aerospace and marine exploration, environmental protection, food safety and other industries.

       An experimental analytical instrument is an instrument used to measure the composition, structure and other properties of a substance. The experimental analysis instruments mainly include chromatograph, mass spectrometer, spectrometer, spectrometer, energy spectrometer, electrochemical analyzer, thermal analyzer, etc. Among them, spectrometers, mass spectrometers, chromatographs and laboratory equipment are its most important product branches.
