The ultrafine aerosol monitoring instruments for real-time Nano air quality studies, called SMPS, are compact, portable and with a sophisticated optical laser light detection system to monitor the particle size from a few nanometers upwards and their size distribution in many different size ranges up to one micron. Combining the SMPS with optical spectrometers, a full airborne aerosol size range can be monitored with one compact system.

A range of many different modular Condensation Particle Counter (CPC) models and the Faraday Cup Electrometer (FCE) for the measurement of the number concentration of Nanoparticles, Differential Mobility Analysers (DMAs) for the size distribution in different size ranges, several Neutraliser types and many accessories offer the possibility to set up an individual system configuration.
