Abstract:
The Portable Ultrafine Particle Sizer (PUPS) invention is provided. The PUPS is an instrument which can measure particle number concentration for particle sizes under 200 nanometers in-situ. The PUPS is a compact design for quick mounting on vehicles. Size discrimination is accomplished using a compact reverse Differential Mobility Analyzer (rDMA). Particle charging is accomplished using corona ionization. Concentration measurements are completed using a unique flexible printed circuit board electrode which can be removed for cleaning, disposal or chemical analysis of collected particles at the end of its in situ measurement life.
