To do so, the size distribution is acquired as a function of position in a flow-through resonator. Considering the size range of the aerosols investigated and the mean free path of air molecules, the acoustophoretic phenomenon reported here falls in the transition and molecular regimes. An electrostatic transducer is used to generate a standing wave in the 50-80 kHz frequency range, concentrating the particles at the pressure nodes. A section of the flow is then sampled isokinetically and sent to the analysis system which provides quantitative data on size distribution. The results demonstrate the possibility of performing acoustic separation on aerosols with particle diameters as small as 100 nm.
