摘要
针对大气中过氧乙酰硝酸酯（PAN）在线监测需求，研制了基于气相色谱配电子捕获检测器（GC—ECD）技术的大气PAN在线分析系统。详细描述了该系统总体设计及主要构成单元结构，展现了系统中各模块功能特点。对该系统进行了性能测试，结果显示该系统性能稳定，线性良好，检出限低；具备可靠性高，稳定性好，分析周期短，维护量小等特点；能较好的满足大气PAN现场在线监测需求。
An on-line analytic system based on gas chromatography and electron capture detection （GC-ECD） was developed for the analysis of atmospheric peroxyacetyl nitrate （PAN）. The overall design and configuration of the analytic system are described in detail, and the function of each unit is demonstrated. The performance tests revealed that the analytic system has stable performance, good linearity, and low detection limit. And the analytic system has the advantages of high reliability and stability, short circulation time, and little maintenance, can meet the requirement of field on-line analysis applications.
