Scanning electrical mobility spectrometer [PDF]

Journal of Aerosol Science, 1989
The measurement of particle size distributions using electrical mobility can be accelerated significantly by an alternate mode of operating mobility instruments. Rather than changing the electric field in discrete steps to select particles in a given mobility range, the electric field can be scanned continuously.
