TSI 8525Ultrafine particle counterSolution
P-TRAKTMUltrafine particle counterThe same technology as TSI's Condensed Particle Counter (CPC) was applied. The latter has a decades long history of application in particle source detection and recording, and has been widely used in scientific research and industry worldwide.
P-TRAKTM can detect particles with a diameter less than 0.1 micrometers and count them. It is generally believed that these particles are often accompanied by the presence of pollutants, so the pollution source can be identified through P-TRAKTM detection. Whether it is obvious sources of pollution (such as boilers, motor vehicles) or non obvious sources (such as copiers, printers), it is difficult to deceive P-TRAKTM. It can successfully identify the migration of toxic gases, office facilities with pollution problems, production workshops, leaks of boiler gaskets, and many other issues.

Then you may need to perform measurements such as volatile organic compounds (VOCs), toxic gases, bioaerosols, and suspended particle concentrations (TSP/RSP). Even so, you may still not be able to find the source of the pollution. What is the problem?
Many persistent air quality issues are to some extent related to ultrafine particles. Particles with a diameter less than 0.1 micrometers are usually products of combustion or other chemical reactions. These tiny particles may be generated indoors or outdoors, and their sources include motor vehicle emissions, chimney emissions, industrial processes, battery charging, filter leaks, smoking, kitchens, dry cleaners, cleaning agents, office equipment, etc. As far as humans are concerned, the reactions of different individuals to ultrafine particles vary greatly, but sometimes they can be very strong.
