For harmonization of sampling and measuring methods regarding in-stack measurement of PM_<2.5> and PM_<10> mass concentration and condensable particles in flue gas of stationary emission sources, such as factories and power plants, international standard methods using a virtual impactor and using a diluter were developed in this research. Both methods have been published as ISO 13271 and 25597 based on this research. In the process of standardization, the performance of VIS impactor was compared with that of a commercial, conventional two-stage cascade impactor collecting particles on solid impaction plates. The virtual impactor measurement provided consistent data in model aerosol testing and flue gas sampling from test and commercial plants of coal and other fuel combustion in Japan, Malaysia and China. At each plant, the condensable nanoparticles were also sampled, and organic and inorganic trace elements were measured by the collaboration with other groups in this project.
