Abstract: The lifetime of aerosol monitoring, concentration and collection equipment is extended by acoustic cleaning of accreted particle deposits from internal surfaces where fouling occurs by application of acoustic energy to the particle accretion surface, optionally in combination with a liquid wash or sampling volume. In one application, acoustic cleaning or sampling of particle deposits for analysis is triggered by a signal indicating changes in gas flow associated with particle loading. In another application, electro-acoustic transducers may be used to prevent particle buildup without interruption of particle monitoring.
