摘要
本文结合我国环境监测现状,对空气挥发性有机物在线监测技术现状进行了研究与探讨,主要介绍了气相色谱法、气相色谱-质谱法、质子转移质谱法和飞行时间质谱法,并对基于上述方法原理的相关在线监测设备和厂商进行了梳理总结。目前,空气中挥发性有机物在线监测设备主要是应用氢火焰离子化检测器的气相色谱法,该类设备结构简单、稳定性好、响应迅速、维护成本低,因此在空气在线监测中应用广泛。
In this study, according to the current situation of environmental monitoring in China, the development of on-line monitoring technologies for volatile organic compounds(VOCs) in ambient air, including the methods of gas chromatography(GC), gas chromatography-mass spectrometer(GC-MS), proton transfer mass spectrometer(PTR-MS) and time of flight sass spectrometer(TOF-MS), were introduced and discussed in detail. Furthermore, the on-line monitoring devices for the above techniques of detection and the corresponding manufacturers were systematically summarized, respectively. At present,it is generally accepted that the GC equipped with flame ionization detector(FID) is widely used as the optimal on-line monitoring equipment for VOCs in ambient air, due to the simple structure, the decent stability, the rapid response and the low maintenance cost.
