- Real-time aerosol measuring instruments have been widely used for the measurement of atmospheric aerosol, diesel
particulate matter, or material synthesis. A scanning mobility particle sizer (SMPS) measures the number size
distribution of particles using electrical mobility detection technique. An aerodynamic particle sizer (APS) is used to
determine the number concentration and the mean aerodynamic diameter of test particles. An electrical low-pressure
impactor (ELPI) is a multi-stage impaction device to separate airborne particles into aerodynamic size classes using
particle charging and electrical detection techniques. In this study, the performance of these instruments were evaluated
to assess their ability to obtain mass concentrations from particle number concentration measurements made as a
function of particle size. The effect of determination of particle density on the measurement of mass concentration was
investigated for the three instruments.
