Abstract：This paper describes the setting-up of a characteristic spectrum library of PM2.5 online source components in Tianjin by means of SPAMS (single particle aerosol mass spectrometer) based on the results of source apportionment of particulate matters in Tianjin, several typical PM2.5 emission sources, such as flying dust, coal-burning, motor vehicle exhaust, industrial production, biomass combustion, cooking fume of catering business, and etc. The analysis of the data acquired was determined by ART-2a, an adaptive and clustering algorithms method, and thus the spectral characteristics of the components of PM2.5 in Tianjin were determined. According to the results of correlation analysis of PM2.5 composition off-line and online measurements, it was concluded that being enough to reflect the basic information regarding various contaminants the online source apportionment spectra of various pollutants were of good representativeness, so it could be used for matching the online source analysis receptor samples.
