Chasing a passenger car with a mobile emission measurement laboratory

In addition to our stationary labs, we employ a mobile laboratory to chase emission sources.


  • Main laboratory for building and testing instruments
  • Aerosol synthesis lab (Flame lab)
  • Emission lab
  • Calibration lab
  • Mobile laboratory


Measuring Equipment

We use the latest and most up-to-date instrumentation available to study aerosols. This includes (but is not limited to):

  • Api-Tof by Tofwerk
  • Aerosol Mass Spectrometer (AMS) by Aerodyne
  • Traceable particle number concentration calibration with SCAR (Singly Charged Aerosol Reference, developed in our lab by Yli-Ojanperä et al.)
  • Condensation Particle Counters (CPC) by TSI and Airmodus
  • PSM by Airmodus for sub-3 nm particles
  • ELPI and ELPI+ (Electrical Low Pressure Impactor) by Dekati

Mobile Measurements

Our mobile measurement laboratory is a special van equipped with sampling inlets in the front, a weather station and GPS, and batteries to sustain hours of mobile measurements.

Measurements in urban settings and near aerosol sources require an adapting and mobile infrastructure. Our mobile laboratory (lovingly named “The Manatee”, due to it’s large and grey appearance) acts as a shelter for sensitivie instruments and provides their electricity. It also has a variety of inbuilt and well-charaterized sampling inlets for particle and gas measurements.  The associated mobile smog chamber is designed to study photochemical aging of sampled aerosols.

In addition to studies of aging and secondary formation of urban and emission aerosols, the mobile laboratory can be used to measure roadside aerosols and study dispersion of traffic and urban emissions. The laboratory also enables on-road studies within real traffic setting.

The mobile laboratory infrastructure is Tampere University’s contribution to the Finnish INAR RI and the European ACTRIS infrastructures.
