Abstract:

The theory of operation of aerodynamic particle sizer spectrometer and tapered element oscillating microbalance are different, and the data types of two measurements are also different. Using the aerodynamic particle sizer spectrometer, the data of particle size distributions were measured in three seasons (winter, spring and summer) in Beijing. Using three instruments of model R&P1400a, the data of PM10, PM2.5 and PM1.0 were measured. According to the correlation comparison of the data of two analysis methods, the data correlativity of aerodynamic particle sizer spectrometer and tapered element oscillating microbalance was obtained. The regression equation of two measurements was established.

Key words: particle sizer spectrometer, tapered element oscillating microbalance, mass concentration, regression analysis
