Abstract
The conceptual design and evaluation of a fine particle sizing and counting instrument are introduced in this paper. A corresponding laboratory prototype was developed by coupling aerodynamic particle focusing with corona charging techniques that could detect particle sizes down to 25 nm in diameter. Comparison between the prototype and a condensation particle counter (CPC) using identical monodisperse particles showed that the measurements agreed well for the particle sizes in the range of 60–300 nm.
