Description:
An aerosol mass monitor has been built to measure the masses of non-volatile aerosols in the range of 0.05 to 5 micrometers aerodynamic particle diameter. The instrument consists of a newly designed spiral duct aerosol centrifuge equipped with highly sensitive quartz sensors for in situ weighing of the deposited aerosol masses. The instrument further includes a clean air device for maintaining constant aerosol flow conditions, and electronic parts for the operation of the quartz sensors. The mass of aerosol deposited on the quartz crystals is automatically measured by an electronic counter while the rotor of the centrifuge continues spinning. The data are handled by a microprocessor.
