To accelerate measurement of particle size distributions by a differential mobility classifier (DMA) with a condensation nuclei counter (CNC), a computer-controlled rapid stepping mode was developed as an operation method. The rod voltage of DMA was varied stepwise every 6 seconds to select particles with a given mobility. Thirty aerosol concentrations were measured within 200seconds. Our system showed a 12 second time-delay between voltage shift and aerosol concentration response. After adjustment of the time-delay, the size distribution ranging from 0.014 to 0.373 μm was determined by a stepping mode analysis (Adachi, 1990). For polystyrene latex aerosol and sodium chloride aerosol, the size distributions measured with the rapid stepping mode agreed with those measured by the ordinary stepping mode.
