The National Institute for Occupational Safety and Health Spokane Research Laboratory sponsored this project to develop a portable sampler capable of collecting nano-scale airborne particulate matter. The samples will be analyzed using electron microscopy to characterize potential hazards to exposed workers. Using thermophoretic precipitation technology, our team developed an efficient and portable design for the sampling device itself. Data collected from a prototype testing session was used to advance the design toward efficiency, portability, and usability. The Gonzaga team worked in partnership with an electrical engineering design team from Eastern Washington University to develop the control systems.
