With the increasing industrial activities and the following combustion emissions, people gradually realize that the emission of ultrafine particles may cause air pollution. Thus, atmospheric research institutes for aerosol generation and migration are paying more attention to those ultrafine particles with particle diameters <0.1 μm. Palas® SMPS scanning mobility particle sizer can provide accurate monitoring data of particle size distribution from 4 nm to 1.2 μm. With its high-precision performance and smooth field operation, Palas® SMPS is worthy of the choice and trust of ultrafine particle research institutes.
Precise classification by electric mobility
Palas® SMPS is mainly composed of two parts: Differential Electrical Mobility Classifier (DEMC) and Condensation Particle Counter (CPC). They are used for particle classification and particle number concentration counting. During monitoring, firstly the sheath air goes into DEMC, and then the classification of different particles can be done through voltage regulation. After that, CPC counts single light pulses at the DEMC outlet to calculate particle number concentrations of each particle size channel. With the help of SMPS, the precise particle size distribution of the sample can be obtained easily.
A wide range of applications with outstanding performance
With its outstanding principle of operation – electric mobility, Palas® SMPS has been widely recognized in field operations. It has previously conducted UFP monitoring at Airport Zurich. The graph below shows the relevant monitoring data 400m away from the runway. The red line indicates the mean particle diameter, and the blue line means the total number concentration. As the graph shows, more UFPs appeared at the time of aircraft take-off, with increasing total number concentration. And UFP decreased when there was no aircraft. SMPS can help make airport activities traceable and provide data support for related scientific research.
The Palas ® SMPS also accurately monitored particle emissions caused by ship activity at harbors. As the graph below shows, the total concentration rose sharply at around 21:40, which could be inferred then many ships left. In addition, the significantly changing thermal map also reflects the flexibility and agility of SMPS monitoring.
The Palas® SMPS will continue providing highly-accurate and reliable UFP monitoring solutions, helping scientific institutes accurately grasp the situation of UFP in the air. And Palas® will keep bringing valuable Palas® wits for environmental protection.
