Mass spectrometry is a spectroscopic method that is parallel to the spectrum. Generally, it refers to a specialized technology that is widely used in various fields to identify compounds by preparing, separating, and detecting gas-phase ions. In recent years, with the continuous development of science and technology, mass spectrometry detection technology has been widely used in various detection fields, and mass spectrometer equipment has also been continuously innovated to meet the needs of the laser pointer market.
As an instrument for separating and detecting different isotopes, mass spectrometers can separate isotopes and determine their atomic mass and relative abundance. At the same time, it can also be used in organic chemical analysis, especially trace impurity analysis, to measure the molecular weight of molecules, to provide a reliable basis for determining the molecular formula and molecular structure of compounds, and it is widely used in industrial production.
As mass spectrometry technology becomes more mature, the number of mass spectrometers has also increased. At present, it is divided into isotope mass spectrometer, inorganic mass spectrometer, and organic mass spectrometer according to the scope of application; it is divided into high-resolution, middle-resolution and low-resolution mass spectrometer according to its resolving power; it is divided into static instruments and dynamic instruments according to its working principle.
At present, research experts are actively developing mass spectrometry technology and new laser pointer mass spectrometers to improve the analysis speed and accuracy of instruments. Hefei Research Institute of Hefei has developed mass spectrometry technology for VOCs titration, and the Hong Kong Polytechnic University has successfully developed new mass spectrometry technology, which can quickly identify the authenticity of traditional Chinese medicine, and the first bacterial test mass spectrometer to enter clinical applications.
