"Development of vacuum ultraviolet photoionization nucleation aerosol mass spectrometer"

[ Instrument Network Instrument Development ] On September 26th, the national key research and development plan "Research on the causes and control technology of air pollution", "Development of vacuum ultraviolet photoionization nucleation aerosol mass spectrometer" project passed the technical indicators of Anhui Institute of Optics and Mechanics Inspection and acceptance.
Technical indicator test acceptance meeting venue
During the implementation of the project, the project team developed a prototype of vacuum ultraviolet photoionization nucleation aerosol mass spectrometer by developing a new method for detecting chemical composition of nanoparticles, realizing atmospheric pressure mass spectrometry injection and high efficiency transmission of ultrafine nanoparticles. The chemical composition of ultrafine nanoparticles was obtained from the molecular level on-line detection, and the preliminary application of vacuum ultraviolet photoionization nucleation aerosol mass spectrometer was carried out.
The meeting invited six experts from China University of Science and Technology, China University of Geosciences, Nanjing University of Information Science and Technology and Anhui University to test and demonstrate the technical indicators of the project. The inspection expert group listened to the work progress report of the researcher of the project, Anhui Institute of Optics and Mechanics Tang Xiaofeng, and inspected the vacuum ultraviolet photoionization nucleation aerosol mass spectrometer developed by the project team, and carried out on-site inspection of the technical indicators of the instrument. And argumentation. The expert group agreed that the project results were rich, and the project team successfully completed the technical indicators in the project task book.
