摘要
本文根据环境空气颗粒物水溶性离子连续自动监测系统的结构和工作原理,探讨其校准方法,提出了采样流量、测量线性、示值误差、重复性、检出限等校准项目和性能指标。结果表明:该校准方法能准确可靠地对环境空气颗粒物水溶性离子连续自动监测系统的综合性能进行评价,为溯源工作提供参考依据。
Based on the structure and working principle of the continuous automatic monitoring system for water-soluble ions of ambient air particles,this paper discusses the calibration method and proposes calibration items and performance indexes such as sampling flow rate,measurement linearity,indication error,repeatability and detection limit.The results show that this calibration method could accurately and reliably evaluate the comprehensive performance of the continuous automatic monitoring system for water-soluble ions of ambient air particulate matter,and provide a reference for traceability work.
