<\/p>\nAir pollution has become increasingly severe, causing profound impacts on human health and ecosystems. To deeply investigate the sources and impacts of atmospheric particulate matter, Researcher Wu Zhijun and his team from the College of Environmental Sciences and Engineering at Peking University are committed to studying the generation and growth mechanisms of new particles under complex conditions, as well as the role of aerosol phase transition processes in environmental pollution and climate change, seeking solutions to air pollution. For the research, they chose Palas\u00ae U-SMPS nanoparticle analyzer as a key equipment, which provided strong support for unraveling the mystery of air pollution.<\/p>\n
Palas\u00ae U-SMPS nanoparticle analyzer has been widely used in the field of atmospheric particulate matter research due to its outstanding performance and accurate measurement capability. It can monitor the quantity concentration and size distribution of nanoparticles in the atmosphere in real-time, providing important basic data for the research team.<\/p>\n

Selection of Research Teams in Higher Education<\/strong><\/p>\n Peking University, as a comprehensive institution of higher education with great influence in China, has accumulated rich research experience and achievements in the field of environmental engineering since the establishment of the environmental chemistry program in 1972. As a researcher and doctoral supervisor of the Department of Environmental Science, College of Environmental Sciences and Engineering, Mr. Wu Zhijun is also an outstanding representative of this field. He led his team to achieve innovative results in understanding the evolution of aerosol liquid water content and phase state, as well as the ice-forming activity of particulate matter during heavy pollution occurrence and development. This improved our understanding of the physical and chemical causes of regional atmospheric heavy pollution, while also expanding international research on urban aerosol phase state, water content, and ice nucleus formation in atmospheric science.<\/p>\n In practical applications, multiple sets of nanoparticle measuring instruments are often required in the research to provide particle size distribution information. However, the price of nanoparticle measuring instruments is generally high, and research organizations are often unable to satisfy the need for complete measurement of particle number concentration over a wide range of particle sizes. To overcome this challenge, Dr. Wu and his team chose Palas\u00ae U-SMPS to help their research.<\/p>\n Particle size spectrometer U-SMPS provides critical data<\/strong><\/p>\n Palas\u00ae U-SMPS nanoparticle analyzer is capable of accurately measuring atmospheric nanoparticle number concentration, and size distributions continuously, providing key fundamental analytical data for the study of new particle generation and growth mechanisms. Compared with other similar products, U-SMPS is characterized by its moderate size and high level of integration, which makes it easy to be transported to operate comprehensive atmospheric field observation experiments. In addition, U-SMPS has a wide range of particle sizes, covering 8 nm-1.2 \u03bcm, which solves the problem of missing data in some of the particle size intervals. Meanwhile, the user interface of the instrument has an excellent interactive experience, which can realize the control of the instrument by clicking the screen and displaying the measurement data in real-time, so that it is convenient to grasp the data quality in time.<\/p>\n Comforting service from Palas\u00ae professionals<\/strong><\/p>\n During the cooperation with Palas\u00ae, researcher Wu Zhijun’s team highly appreciated its products and services. Palas\u00ae technical support team provides timely, patient and rigorous guidance on instrument construction, maintenance and data processing to ensure the smooth progress of the research work. In addition, Palas\u00ae also customized a transport case for U-SMPS to ensure the safety of the instrument during transportation, which is a detail that won the appreciation of Mr. Wu\u2019s research team.<\/p>\n Palas\u00ae U-SMPS nanoparticle analyzer, with its outstanding performance and professional service, has provided strong support to the atmospheric particulate matter research team, including researcher Wu Zhijun of the College of Environmental Sciences and Engineering, Peking University, and has laid a solid foundation for future cooperation. Both parties will continue to deepen their cooperation and jointly promote the development of the atmospheric particulate matter research field. Palas\u00ae also looks forward to cooperating with more research institutions to jointly promote scientific research in the field of environmental protection and contribute to the realization of sustainable development of the environment.<\/p>\n Palas\u00ae SMPS universal scanning electric mobility particle size spectrometer <\/strong><\/p>\n The Palas\u00ae U-SMPS Universal Scanning Electric Mobility particle size spectrometer and the ENVI-CPC 100 Condensation Particle Counter work together to provide data on the number concentration and size distribution of ultrafine particles. The two instruments can be flexibly combined and networked according to different needs. In addition, the Palas\u00ae ultrafine particle monitoring system supports DMA, CPC and other manufacturers\u2019 aerosol electrostatic meters. Remotely controlled and unattended, the system is suitable for long-term aerosol research, and climate studies, as well as filtration testing, workplace measurements, or exhaust monitoring, helping to meet the challenges posed by a wide range of ultrafine airborne pollutants.<\/p>\n Product Advantages: Application Areas: Palas\u00ae regularly conducts webinars on a variety of topics to pass on its expertise in aerosol measurement technology, which are presented in detail online by Palas\u00ae technical experts and industry scholars from around the world.
