title: [Comparison Test Between PM2.5 Continuous Monitoring System and Manual Sampling Analysis for PM2.5 in Ambient Air].
abstract: According to the U. S. EPA performance index and detection methods for comparison test of PM2.5 continuous monitoring system, in combination of the current related technical specifications in China, 4 types of typical imported and domestic PM2.5 continuous monitoring system with two different principles were tested and compared to the manual sampling measurement (gravimetric method) in spring, summer, autumn and winter. This research determined the quality control requirements ( parallelism of manual sampling measurement results ≤ 5 µg · m(-3) or 5%), the technical index (slope of linearity regression equation 1 ± 0.15; intercept 0 ± 10; correlation coefficient ≥ 0.95), and corresponding detection methods of reference method comparison test to PM2.5 continuous monitoring system, which meets the requirement of current environmental quality status and environmental monitoring and management in China. It also provided technical means and method of quality control for effective use and data quality of PM2.5 continuous monitoring system in China.
