| 中文摘要: |
| 根据中国环境保护产品认证标准（CCEP）的技术规范，结合美国环境保护署（EPA）关于环境空气监测参考指标和等效检测方法，对赛默飞世尔最新开发的双通道颗粒物自动监测装置的主要性能指标进行分析表征。用3台待测双通道5028i型和2台参照单通道5014i型颗粒物自动监测装置连续2个月自动监测大气颗粒物PM2.5和PM10，考察双通道颗粒物自动监测装置关于仪器精度、仪器准确度、流量稳定性和准确性等方面的性能。 |
| 英文摘要: |
| According to China Certification for Ecolabelling Products (CCEP) technical specification, U.S. Environmental Protection Agency (EPA) monitoring reference index and equivalent detection method on ambient air, main performance indexes of dual channel particles automatic monitoring device newly developed by Thermo Fisher Scientific were analyzed and characterized. During two months of continuous automatic monitoring, results of atmospheric particulates PM2.5 and PM10,were researched using three candidate dual channel monitors (5028i) and two referenced single channel monitors (5014i). Some performance indexes of dual channel continuous ambient particulate monitor such as instrument precision, instrument accuracy, flow stability and flow accuracy were proposed. |
