摘　　要：大气PM2.5/PM10的检测在当今越发重要,其技术核心是检测误差和平行性。为了减小大气颗粒物的检测误差和仪器平行性,该文从PM10和PM2.5分离技术、恒流抽尘技术和细颗粒物浓度检测技术三个方面进行研究,研制了一种适用于大气环境的PM2.5/PM10检测的便携式仪器。实验证明:PM2.5/PM10旋风分离器满足设计要求,颗粒物检测仪误差小于2.2%,平行性误差小于4.8%,符合国家检测标准的要求。The detection of atmospheric PM2.5/PM10 is increasingly important today,and the core of the technology is detection error and parallelism.In order to reduce the detection error of atmospheric particulate matter and the parallelism of the instrument,this article will study three aspects of PM10 and PM2.5 separation technology,constant current extraction technology and fine particle concentration detection technology to develop a PM2.5/PM10 portable instrument suitable for the atmospheric environment.The experiment proves that the PM2.5/PM10 cyclone separator meets the design requirements;the error of the particle detector is less than 2.2%,and the error of parallelism is less than 4.8%,which meets the requirements of national testing standards.
