Exhaust emissions


​We are able to make comprehensive analysis of particulate emissions including size-classification, even nanoparticles by employing different methods and instrumentation.

Mass size classification of particles can be done using virtual impactors for PM2.5 (PM1), and cascade impactors (DLPI, DGI) for both diesel and gasoline emissions, and number size classification of particles using electrical impactors (ELPI, real-time measurement) or using mobility analysers (SMPS, CPC).

In addition we have various options for sample dilution, like full and partial flow samplers or porous tube type dilutors.

Pre-treatment options are available as well, like thermodenuder to remove volatile fraction of particles
