Abstract
A process is disclosed for using multiple acoustic resonators to sample fluids (gas or liquids), capture particulate (or aerosols) entrained in the fluid, and deliver a concentrated sample of particulate. The acoustic concentrator demonstrates many improvements over prior art that includes improved concentration of particulate below 3 micron, adjustability of the level of concentration, ability to function over a wide range of humidity and temperature, and reduced overall power consumption. For example, when installed on the inlet of an aerosol detection system, the acoustic concentrator has been shown to increase sensitivity that may lead to earlier detection of bioaerosol agents.
