Beijing Metrology Institute's particulate reference material passed the national second-level standard substance review meeting

[ China Instrument Network Instrument Development ] On March 14, 2019, the polystyrene microparticle standard material (8 particle sizes) developed by the Beijing Institute of Metrology was successfully passed the National Standard Reference Substances Review Meeting. More than 10 review experts from the Standards Substance Management Committee, Director Shen Zhengsheng from the Ministry of Chemistry, Director Zhang Guocheng of the Institute of Environmental Energy, Zhao Xiaoning, project leader, and members of the research team, Xiao Xiaoping and Liu Chenzhao, participated in the review meeting.

Dr. Zhao Xiaoning of the Institute of Carbon Energy has reported in detail on the synthesis, calibration, value traceability, data analysis and quality inspection of the polystyrene microparticles developed by the research group. The review experts listened carefully to the project report. After questioning and discussion, they agreed that the polystyrene particulate reference materials (eight particle sizes) passed the national secondary standard materials grading and appraisal, and fully affirmed the standards for the Beijing Metrology Institute. The development and production of materials.

With the support of the leaders of the hospital, the comrades of the Central Energy Institute have gathered together and their research capabilities have developed rapidly. The application of polystyrene microparticle reference materials is of great significance to the evaluation of PM2.5 monitor particle size recognition ability and PM2.5 cutter particle size cutting efficiency evaluation by Beijing Metrology Institute. At the same time, it has broadened the business dimension of Beijing Metrology Institute in industrial measurement, and further improved the testing technology and scientific research capabilities of Beijing Metrology Institute.
