With the increasing influence of human actions on the environment, the amount of particulate matter also increases, thus threatening the ecological environment and people’s health. Whether it is smog or just a grey sky, particulate pollutants are ubiquitous. No matter if indoors or outdoors, reliable air quality measurements need reliable instruments. This is where Palas® comes into play. For example, the U-SMPS universal scanning mobility particle sizer developed by Palas® combines the advantages of nanometer measurement, flexible and convenient operation, and accurate monitoring results. Suitable for a variety of research scenarios, it can effectively measure and evaluate air pollution levels. To monitor pollutant emissions and air quality, the researchers chose U-SMPS for ultrafine particle monitoring at ports and airports.
Palas® Ultrafine Dust and Nanoparticle Monitoring
To monitor the particulate emissions of a ship in a port, the Palas® U-SMPS was chosen. Users did benefit from the U-SMPS’ intuitive interface and standalone device with an integrated data logger. The device enables remote control via TeamViewer® and Windows. The monitoring started with the departure of the ship. Thanks to the outstanding features of the U-SMPS the total particle concentration and nanoparticle could be measured and displayed.
In addition to the port, the U-SMPS was also used for monitoring ultrafine particles at an airport. The device was placed at a terminal around 400 meters distance to the runway. The data showed a correlation between air traffic and the amount of particulate matter in the ambient air.
Accurate Measurement for Comparable Data
In both cases, the Palas® U-SMPS delivered the highest size resolution (120 size channels / ten times the particle size) proving its outstanding benefits.
Thanks to the system software PDAnalyze with its one-click automatic data saving no external data recording system and no additional synchronization equipment time was required. Changes in the number of particles with specific sizes became visible. At the same time, the particle size distribution maps can be automatically merged to obtain intuitive data results.
Pure optical detection is limited to particles > 120 nm. While U-SMPS combined size distribution is 4nm to 40,000nm. Palas® U-SMPS is comparable to reference SMPS system at world calibration center (TROPOS, Leipzig). The Palas Nanoparticle Measurement Systems are state-of-the-art instruments, offering the highest flexibility in the market combined with accurate and reliable sizing and counting. With smart solutions and excellent customer service, Palas® offers great alternatives in the market.
