Palas® Guards Urban Ambient Air Quality

As the main pollutant of the ambient air, fine dust particles not only endanger human health, but also affect the ecological environment in the process of urbanization. Multi-dimensional ambient air monitoring data of urban environment can provide reference for further urban development planning and guard the ecological home. Research institutes, including the institutes of environment, focus on comprehensive urban environmental research and require long-term monitoring of a wide range of fine dust particles in the ambient air. The Palas® Fidas® 200 S Fine Dust Aerosol Spectrometer has a flexible application range and can continuously measure PM1, PM2.5, PM4 and other particulate matter at the same time. It provided highly accurate and reliable monitoring data for an institute of environment from April to October 2022.

Stand-out Palas® instrument

With the progress of urbanization, people gradually pay more attention to the current situation of urban environmental quality. Those research institutes, including the institutes of environment, face the major strategic needs of ecological and environmental protection in the process of urbanization. They have strict requirements for the accuracy, flexibility and continuous monitoring capability of ambient air monitoring instruments.

Palas® specialized in particle matter monitoring. The Fidas® 200 S Fine Dust Aerosol Spectrometer is type-approved and certified according to EN 15267 requirements. It can simultaneously measure PM1, PM2.5, PM4, PM10 TSP values, particle size distribution and number concentration at the same time. The Fidas® 200 S also has adjustable time resolution from > 1 s to 24 h based on particle number concentration. The flexible application range led an institute of environment to choose Palas® instrument. This institute used the Fidas® 200 S Fine Dust Aerosol Spectrometer for observations from April 2022 to October 2022 in Xiamen, Fujian Province.

Trustworthy Palas® monitoring data

During the observation period, the Fidas® 200 S Fine Dust Aerosol Spectrometer operated smoothly, and the data obtained were trusted by the institute. The researchers compared the data from the Fidas® 200 S with the commonly used SMPS. And they found that the number spectrum distributions were consistent when the observed particle size ranges overlapped.

At the same time, the Fidas® 200 S Fine Dust Aerosol Spectrometer simultaneously and continuously measured PM1, PM2.5, PM4, and PM10. Researchers remarked favorably the measured PM mass concentrations after comparing that with those measured by conventional instruments.

The Fidas® 200 S Fine Dust Aerosol Spectrometer met the needs of researchers for a wide range of observations. And it can keep operating smoothly with regular and simple maintenance. In late August to mid-September 2022, the Fidas® 200 S Fine Dust Aerosol Spectrometer showed anomalies in the observation data, which were later checked and confirmed to be caused by a clogged inlet pump membrane. Overall, this aerosol spectrometer is suitable for long-term stable use in research institutes and local monitoring platforms.


Palas® Fidas® 200 S Fine Dust Aerosol Spectrometer

Fidas® 200 S is a fine dust aerosol spectrometer developed specifically for regulatory air pollution control. Fidas® 200 S analyzes continuously the fine dust particles present in the ambient air in the size range 180 nm – 18 µm, and calculates simultaneously the emission values PM2.5 and PM10. At the same time, PM1, PM4, PMtot, the particle number concentration CN and the particle size distribution are calculated and recorded by Fidas® 200 S. It delivers comprehensive information about the fine dust particles, only provided by a counting, single particle measuring principle. In addition, it is integrated in the IP65 weatherproof cabinet for outdoor installation (temperature range -20 – 50 °C). It is suitable for both alpine and coastal applications.
