Abstract Emissions from stationary sources such as power plant attracts much attention due to intense emission control in Korea. 26 power plants are located in Chungnam area which is important for the air quality of capital area. Current exhaust particles are monitored using opacity measurement. The measurement results are not size-resolved and small particles under several tens of nanometers cannot be measured. For the size-resolved filterable particle measurement, dilution probe technology are prepared. Continuous, real-time measurement technology for the precise fine particle (PM2.5) monitoring is suggested in this research. Exhaust particles are sampled through dilution probe and are measured light scattering method. EPA method 201a is simultaneously adopted to compare the values. Air flowrate and temperature of dilution air controlled to find optimal measuring condition.
