摘要
随着国内仪器研发技术的不断发展,越来越多的国产颗粒物自动在线监测仪器在市场上占得一席之地。但是,目前对国产仪器性能的实际检验仍然缺乏相关研究报道。分别选取了两款有代表性的国产和进口PM_(2.5)在线监测仪器,进行了长时间段的运行数据比对,并将国产仪器的监测数据与手工采样数据进行了比对。研究结果发现:国产PM_(2.5)在线监测仪与进口仪器相比,性能已十分接近;且其监测结果与手工采样结果相比亦基本符合国家标准。由此表明,PM_(2.5)在线监测仪经适当改进后在国标范围内是可以替代进口仪器的。
With the continuous development of the domestic instrument research technology, an increasing number of domestic equipment has earned larger market. However, relevant research report on the actual performance inspection of domestic equipment was still insufficient. This study had selected representative domestic and imported PM2 5 particles automatic online monitors, compared data through a long period of operation, and also compared the monitoring data and manual sampling data of domestic instruments. The results showed that performance of two kinds of instruments were very close, while compared with manual sampling data, the monitoring results were largely in line with national standards. Thus, the PM2. 5 line monitoring device can replace imported equipment through the proper improvement within the scope of national standard.
