Abstract: Particle size distribution and chemical composition of the primary particles have significant influences on the formation of haze and human health. In order to understand the size distribution of the primary particles, a resuspension sampling device had been developed which was based on the calculation of particle correlation theory. The stability of the device was evaluated. The results indicated that:The quantity of TSP, PM10 and PM2.5 samples were analyzed by variance analysis. F values were 0.42、0.07 and 1.34 and far less than F0.95(2,17). The variance analysis of PM10/TSP and PM2.5/PM10 was conducted, respectively. F value was 0.53 which was far less than F0.95 (9, 19)=3.59. The results demonstrated that the particles could be uniformly distributed in the resuspension cavity. The sampling device was able to satisfy the requirement of size classification of primary particles.
