A mass spectrometer is a type of instrument that ionizes matter particles (atoms, molecules) into ions, separates them by appropriate electromagnetic fields, and detects their strength for qualitative and quantitative analysis. Due to its direct measurement nature and high sensitivity and high resolution, it is widely used in environmental monitoring, food safety, new drug development and life sciences. In China, the analytical instrument equipment represented by mass spectrometer has always had the problem of insufficient core technology and serious “hollowing†phenomenon. The mass spectrometer market that has been expanding year by year has been monopolized by foreign companies. The China Institute of Metrology, Fudan University, and Tsinghua University have been undertaking research on the development and development of mass spectrometers since 2004.
The research team adhered to the road of combining original innovation, integrated innovation and introduction-digestion and absorption-re-innovation. After more than two years of research, it has achieved a series of innovative scientific and technological achievements. All key components except the turbomolecular pump and electron multiplier are independently researched, designed and processed by the research team, and the key components and the whole machine have reached a high level of technology. Through the implementation of the project, the research team also established an open platform for mass spectrometry and mass spectrometry, and cultivated a well-structured R&D team.
At the acceptance meeting, experts believe that the mass spectrometer, including the four-pole GC-MS, linear ion trap GC-MS and linear ion trap LC-ESI-MS, and a series of key technologies The successful development of key components has marked a good beginning for the research and industrialization of mass spectrometry and mass spectrometry in China, and has a groundbreaking significance for China's mass spectrometry industry.
My first mass spectrometer was successfully developed.
Recently, the "Development and Development of Mass Spectrometers" in the "Scientific Instrument Development and Development" project of the "10th Five-Year" Science and Technology Research Project passed the acceptance test in Beijing, which marked the high-performance linear ion trap liquid phase with independent intellectual property rights. Chromatography-mass spectrometry and gas chromatography-mass spectrometry have been successfully developed in China for the first time.
