At the beginning of this year, the Ministry of Ecology and Environment released a revised national ecological environment standard with the title \u201cTechnical Requirements and Detection Methods of Continuous Automatic Monitoring System for Ambient Air Particulate Matter (PM10 and PM2.5)\u201d. This new HJ 653-2021 regulation, better known as HJ 653 Technical Requirements, is a game-changer. It is designed to help further reduce the concentration of ambient particulate matter by supporting light scattering monitoring technology. In order to better serve the Chinese market, Palas\u00ae established a subsidiary in China in July 2020. From the beginning of its establishment, it has been preparing for the applicability test of Single Particle Aerosol Distribution Spectrometers (SPADS) in various cities of China. Since Palas China starts, we make “circle tests” across China (incl. Beijing, Shenzhen, Shanghai, Tianjin, Jiangsu, Hebei, Shandong, Sichuan, etc.) to collect data and upgrade accordingly algorithm for China only. HJ 653 is the highest & most strict regulation worldwide based in our understanding and a real challenge which Palas is doing great for it.<\/p>\n

The Light scattering Monitoring Technology in focus
\n<\/strong>The new HJ 653 Technical Requirements brings changes based on two key aspects:<\/p>\n

\u00b7\u00a0 \u00a0Stricter specifications
\n<\/strong>Slope and intercept are tightened for comparison between gravimetric and continuous monitoring instruments;
\n
\n\u00b7\u00a0 \u00a0 Opening to new technologies
\n<\/strong>Limitation to technology (i.e. Beta and TEOM) was lifted. That means, end users have options to benefit from the advanced light scattering technology.<\/p>\n

Users could get benefit from the innovation and maturity of light scattering monitoring technology with significant cost advantages.\u00a0In the European and American markets, light scattering monitoring instruments are on the rise.\u00a0\u00a0The HJ 653 Technical Requirements embracing this monitoring technology trend, will support technological innovation and enables more options to choose from.<\/p>\n

Light scattering Monitoring Technology Expert – Palas\u00ae<\/strong><\/p>\n

Palas\u00ae team has used the Single Particle Aerosol Distribution Spectrometers, Fidas\u00ae series in Beijing, Shenzhen, and Jiangsu to conduct tests. So far, all measurement data in Beijing show that the testing result of PM2.5 have a high correlation with that using manual gravimetrical measurement methods. The data tested in Shenzhen also concluded the parallelism of PM10 and PM2.5 was about 3%. It was found at a test point in Jiangsu that the degree of matching between PM10 and \u03b2-ray automatic monitoring equipment was high.<\/p>\n

Data Validation Light scattering Monitoring Efficiency<\/strong><\/p>\n

Palas\u00ae Fidas\u00ae is based on the patented single particle counting aerosol particle size distribution spectrometer principle. It is a leader in the light scattering\uff0cmonitoring instrument for particulate matter, and a leading brand in the European market. The applicability test of Fidas\u00ae series in China keeps moving. In order to better understand the situation in various places, and to better optimization algorithm and parameters. The tests will also be extended to typical places, such as Hebei and Shandong. Through these tests, Palas\u00ae\u2019s instrument applicability can be optimized, and better experience can be provided to the customers. Palas\u00ae looks forward to cooperating with more partners and owners to jointly serve the market demand for particle monitoring!<\/p>\n
