label: nucleation particle size spectrometer (en)

label: Instrument designed for measuring the number size distribution of particles in an aerosol sample by exposing the particles to an atmosphere supersaturated with evaporated working liquid, thereby activating them to growth by vapour uptake from the gas phase, and counting them optically. The threshold diameter for particle activation depends on the supersaturation. By svanning through the supersaturation, a number size distribution at nano particle sizes can be infered. (en)
