[China Instrument Network Instrument R&D] On April 22nd, the National Key Scientific Instruments and Equipment Development Project “Engineering Research and Application of High-precision Quadrupole Mass Spectrometers” led by the Institute of Mechanical Manufacturing Technology of the Chinese Academy of Engineering Physics was approved. The comprehensive acceptance by the Ministry of Science and Technology was the first item of the instrument special project that passed comprehensive acceptance. More than ten experts and scholars such as Academician Jin Guojun from Tsinghua University, Prof. Zhang Xinrong from Tsinghua University, and President Li Jinying from the China Mass Spectrometry Society participated in the project acceptance review as acceptance experts. Deputy Director Wu Xueti, Department of Resources Allocation and Management of the Ministry of Science and Technology and Deputy Director Mao Jianjun of the Science and Technology Evaluation Center of the Ministry of Science and Technology also attended the acceptance meeting.

The project leader Wang Baorui’s researcher reported to the expert group on the implementation of the project. As of the acceptance of the project, 200 core key components (quadrupole mass analyzers) have been developed, with 2 sample pretreatment equipment, 1 database, and 1 operating software. Applied for 14 invention patents, authorized 3 invention patents and published 17 related papers; technical data that has been formed in engineering includes 11 sets of engineering processes, 8 sets of engineering drawings, and 3 sets of quality and reliability guarantee programs. 1 sets of technical archives; relevant pilot production lines and R&D bases have been established.

After earnestly reviewing the materials and inquiries, the expert group believed that: The project has been implemented in a good condition, the overall progress has been normal, and the progress and results output have met the assessment targets required by the task book; various types of high-precision quadrupole mass analyzers and quadrupole masses have been developed. Analytical instruments for precision measurement of special equipment and test platforms, and development of theoretical models and calculation methods for quadrupole mass analyzers, and demonstration applications in concentrating science and technology, Jiangsu Tianrui, and General Analysis and other applications and industrialization units; projects are strictly followed The requirements of the instrument's special management standards, focusing on engineering and quality and reliability work, and having a basis for mass production capabilities and industrialization, can promote related technological progress and enhance innovation capabilities.

Wu Xuetai, Deputy Director of the Department of Resources Allocation and Management of the Ministry of Science and Technology said at the meeting: I hope that the project team as a research and development centerpiece of scientific instruments will strengthen cooperation with domestic and foreign mass spectrometry instrument research and production companies and continuously improve the core of related products. Competitiveness. In addition, it is also hoped that domestic companies and companies that develop and produce mass spectrometry instruments should have a sense of mission and responsibility, and work together to support domestic mass spectrometer manufacturers to continuously improve and improve product performance, and jointly contribute to the domestic mass spectrometry development.

It is understood that the Chinese Academy of Engineering Physics research on mechanical manufacturing technology "is aimed at solving the problem of localization of core components of domestic scientific instruments". It has successfully developed a precision machining machine for quadrupole mass analyzer parts, achieving the finalization of the manufacturing process and forming a high level. Accuracy, serialization, and mass production of parts. According to user requirements, custom metal, ceramic, ceramic gold plating, metal hyperboloid pole and other specifications of the quadrupole, and can provide fast quadrupole maintenance and repair services.
