APPARATUS AND SYSTEM FOR CHARACTERIZING AN AEROSOL PARTICLE FLOW |
摘要 |
An apparatus and method for improving aerosol particle characterization and detection accuracy in clean room applications that includes an optical particle sizer that receives a particle containing aerosol sample at a higher flow rate which is operatively coupled to an inertial aerosol concentrator for concentrating particles received from the optical particle sizer and delivering a lower flow rate, particle enriched output. The system further includes an optical sensor for sensing of intrinsic particle fluorescence of the lower, particle-enriched flow, since intrinsic fluorescence is a useful indicator of biological particles and biological particle viability, including bacterial particles. The system as a whole provides a measure derived from a single inlet flow both of total particles and of viable microbial particles based on their spectroscopic properties. |
