Outline of Final Research Achievements

A highly sensitive detecting method for suspended particulate matter using quartz crystal microbalance was newly developed. In this method, suspended particulate matter is adsorbed directly to various thin films on the quartz crystal surface to form chemical compounds, and then oscillator frequency of the quartz crystal microbalance is decreased due to the mass increase of the electrode. The new method enables the measurement of low SPM concentrations. We clarified the relation of effective measurement flow rate and measurement time. In addition, analysis by a scanning electron microscope and energy dispersive X-ray apparatus revealed the properties of SPM.
