The scanning mobility particle sizer (SMPS) is a particle size spectrometer that measures the aerosol number size distribution by sizing particles based on their electrical mobility diameter using a differential mobility analyzer (DMA) and by counting particles using a condensation particle counter (CPC). It measures aerosol concentration and aerosol particle size distribution in the Aitken mode range.
