To better understand the health effects associated with ultrafine particles, there is a need to complement traditional parameters (PM10 and PM2.5) by establishing networks to routinely monitor ultrafine particles. The TSI 3031 Ultrafine Particle Monitor has been specifically designed for long-term, air quality monitoring networks.
The 3031 operates continuously, 24-hours a day, for months on end, with minimal maintenance and requires no working fluids. It does not have a radioactive source, so there are no special licensing requirements and no restrictions for its use or where it can be installed. It fits into a standard 19-inch, rack mount cabinet, which allows it to be easily installed into existing roadside and urban air quality monitoring stations. A bench top version of this instrument (3031-1) is available for laboratory or mobile applications.
Developed under the auspices of European Union UFIPOLNET project, the 3031 has demonstrated it is well suited for long-term, ultrafine particle monitoring. Since the beginning of 2007, four UFP monitors have been routinely monitoring ultrafine particles in Stockholm, Dresden, Prague and Augsburg.
More recently, the 3031 was selected by Delaware’s DNR- Division of Air Quality Management for its proven ability to continuously count particles on the nano scale. The results generated from this study will help determine the necessity of future regulations regarding nano emissions.
