摘要
自行开发并研制了 TSP-PM1 0 -PM2 .5-2型中流量 TSP、PM1 0 、PM2 .5大气颗粒物采集系统 ,是目前中国唯一可以采集 TSP、PM1 0 、PM2 .5样品并提供足够的样品量进行大气颗粒物化学成分分析的中流量大气颗粒物采集器。该系统精心设计和加工的限流孔可以保持完全固定的流量 ,保证切割粒径的稳定 ,减小采样的误差并方便操作。该系统已经成功地应用于 2 0多个城市和地区大气颗粒物的监测和研究中 ,为研究大气颗粒物的污染状况和来源提供了有效的技术手段和支持。
The authors design and develop the Model TSP PM 10 PM 2 5 2 medium volume sampling system for collection of TSP, PM 10 , PM 2 5 which is unique in China that could sample TSP, PM 10 , PM 2 5 particles with enough sample amount for chemical analysis The deliberately designed and fabricated metering hole ensures fixed flow rate and stabilize the cutting diameter It could reduce the sampling errors and provide convenient operation as well The system has been successfully utilized in over 20 cities and areas, supporting the research of pollution status and source analysis of particulate matters
