SMPS

smps > Scanning mobility particle sizerInstrument Type(s) > Baseline • Guest

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.

The SMPS can measure the aerosol number size distribution in the particle diameter range from 10 to 500 nanometers (Regular SMPS) and from 2 to 150 nanometers (Nano SMPS).

The SMPS is part of the aerosol observing system (AOS).
