WebThe performance of the Electrical Low-Pressure Impactor (ELPI) has been evaluated using monodisperse aerosols. ELPI is a near real-time size analyzer consisting of an aerosol charger and a cascade impactor. Particle cut sizes of the cascade impactor and the charging efficiency of the charger were determined experimentally in the designed range ... WebIn reality, the collection efficiency of a stage smoothly increases with particle size as an "S-shaped" curve, from approximately 0% to 100%. Consequently, in some cases …
