PSMPS
NANO MOBILITY PARTICLE SIZE SPECTROMETER
Nano mobility particle size spectrometer for the size range 1.1 to 55 nm
The PSMPS is a mobility particle size spectrometer that combines a Grimm SMPS+C system with the Airmodus Particle Size Magnifier (PSM). This combination allows accessing the 1 nm particle size range and offers the metrological coverage of the sub 2 nm size range that is indispensable for under-
standing the basic mechanisms of the highly dynamic processes of particle formation.
In studies on aerosol particle nucleation, the measurement of aerosol number size distributions starting from the sub 2 nm size range is crucial in order to understand the basic mechanisms of new particle formation (NPF) as well as the formation rate and growth rate of the particles (e. g. Kulmala et al., 2013, Direct Observations of Atmospheric Aerosol Nucleation. Science, 339, 934).
Particle nucleation processes are important in the atmosphere where they affect the formation of clouds and the radiative forcing but also in combustion related studies (e. g. the emissions of vehicle engines) and in material sciences (e. g. the synthesis of nanoparticles).
