Aerosol Science Experimental Facilities

Breeze tunnel The aerosol science lab has an array of experimental capabilities and personnel expertise to perform basic and applied aerosol research. Test facilities include several large aerosol test chambers and aerosol wind tunnels to produce a wide range of very controlled aerosol environments. The facilities and labs are supplied with sophisticated aerosol characterizing equipment and instrumentation, data logging capabilities, chemical and biological hoods, and sample preparation areas. These facilities are applied to a spectrum of aerosol science from basic aerosol experimentation to performance characterization of prototype and commercial aerosol collection/detection systems.
