In recent years, China’s total emissions of air pollutants have decreased year by year. However, the task of air pollution prevention and control is still very arduous for China, which is facing the double pressure of relatively unfavorable meteorological conditions and a significant increase in pollution emissions. The Air Pollution Causes and Control Group of the School of Environmental and Chemical Engineering at Shanghai University, which has long been engaged in research on the causes, sources and control of complex atmospheric pollution, used the Palas\u00ae SMPS 2050 Universal Scanning Electric Mobility particle size spectrometer to measure and analyze the particulate matter in their experiments. The Palas\u00ae device provides a graphical display of the measurement results and supports multiple interfaces and remote access, which helps to better observe the experimental data and provides strong support for the research.<\/p>\r\n

As a national “double first-class” construction university, Shanghai University has outstanding achievements in academic research. The Air Pollution Causes and Control Group in the School of Environmental and Chemical Engineering of Shanghai University has long been engaged in the research on the causes, sources and control of air pollution, and is committed to exploring the mechanism of air pollution generation and elimination, and proposing pollution control strategies. In recent years, the group has continued to focus on the areas of formation mechanism, transformation process and pollution sources of secondary pollution of particulate matter, and has achieved abundant research results. On this occasion, they used the Palas\u00ae SMPS scanning electric mobility particle size spectrometer to measure the particles generated by the oxidation of gases by OH radicals in an oxidizing flow reactor. The Palas\u00ae SMPS not only meets the laboratory’s testing needs, but also has excellent stability and consistency. It ensures the reliability and reproducibility of the experimental results and provides a guarantee for the accuracy of the experimental data.<\/p>\r\n

Real-time data display, stable and reliable<\/strong><\/p>\r\n

The Palas\u00ae SMPS is capable of measuring particle size and number concentration of particulate matter in real time. Test data can be viewed in real time on the device display and also in a file in txt format, which allows researchers to quickly analyze experimental data in depth. This real-time data and analysis capability greatly improves research efficiency. In addition, the UF-CPC 50 can be used separately to guaranteeing the smooth running of RTD experiments.<\/p>\r\n

For scientific research, the stability and reproducibility of experimental results are crucial. The Palas\u00ae SMPS system ensures the reliability of experimental results with its excellent stability and consistency. It can help researchers to be able to get consistent data in different experiments, so as to better explore the complex mechanism of air pollution.<\/p>\r\n

Unique Technical Advantages<\/strong><\/p>\r\n

The Palas\u00ae SMPS universal scanning electric mobility particle size spectrometer has a logarithmic scanning mode with no dead time and scanning times of up to 20 seconds. It also allows free selection of the scan time, size range and scan direction (upward or downward scanning). In addition, the SMPS automatically determines the residence time (delay time between the classification column and the counter), minimizing the impact of the experimental setup as no tube length measurements are required.<\/p>\r\n
