Abstract
The invention relates to a method and device for simultaneously measuring mass concentrations of particulates with different sizes. The method detects particulates within different size ranges in air based on laser scattering and can eliminate cross interference between the particulates within different size ranges. The device is simple in structure, can realize on-line simultaneous measurement of PM1.0, PM2.5 and PM10 with high measurement precision and low cost.
