Measurement of the electrostatic charge in airborne particles: I - development of the equipment and preliminary results

摘要: The design and construction of a equipment capable measuring the electrostatic charges in aerosols, named charge classifier, were carried out. They based on concept particle electromobility classifier was intended to classify nature distribution as function size. resulting piece is easy dismount, which facilitates its cleaning transport, operate. Early results indicate that values measured test particles are inside range reported literature, indicating adequacy technique utilized.
