Abstract：The measuring method of fine particulate matter PM2.5 concentration and the metrological traceability of instruments as well as the testing method of standard devices and separator characteristics were introduced. The preparation of standard particles used in testing was discussed. The instruments used to measure the separator characteristics of PM2.5 sampler were developed. A series of standard particles with the sizes between 1.0 and 4.0 μm to calibrate the characteristics of sampler separator were prepared. The research on quantity dissemination method and accuracy testing method of the inhalable particulate measuring devices were carried out. Through the research work, the reference method of testing PM2.5 can be established and the detection data of PM2.5 can be traced to the mass standard.
Keywords：fine particulate matter (PM2.5) ; standard particle; cutting characteristics
