大气细粒子中水溶性有机碳(WSOC)的在线监测

On-line Measurement of Water Soluble Organic Carbon(WSOC) in Ambient Fine Particle

基于一种新型的大气颗粒物在线水萃取采样装置(PILS),通过该装置与快速有机碳分析仪的连接,建立了大气细粒子水溶性有机碳(WSOC)的在线监测系统(PILS-WSOC)。实际运行结果表明,该系统能够快速稳定地获得大气细粒子中WSOC的实时变化数据。与滤膜法的平行实验结果相比,PILS装置对大气颗粒物中WSOC的采样效率远高于滤膜法。

Base on an advanced ambient particle into liquid sampler （PILS）,an on-line system for measuring water soluble organic carbon（WSOC） in ambient fine particle was established by connecting PILS to an organic carbon analysis instrument.This system was named as PILS/WSOC.The field evaluation results of this system show that real-time variation date of WSOC in ambient fine particle can be provided rapidly and steadily.The parallel experiments between PILS and filter sampler indicate that PILS is more available in collecting WSOC than filter sampler.
