简述了国内外监测分析方法中运用气相色谱法检测气体中挥发性卤代烃在采样方法、检测器、检测范围和目标化合物等方面的区别,给出高温高湿条件下污染源废气的样品采集方法。针对污染样品和车间空气样品应使用FID检测器,环境空气样品应使用ECD检测器,同时进一步提出应尽早制定污染源排气中挥发性卤代烃的检测标准方法。
In this paper, the differences between the methods of detection, the detector, the detection range and the target compounds of volatile halocarbons in gas by gas chromatography are described briefly in the domestic and international monitoring and analysis methods. The sample collection of the pollutant exhaust gas under the condition of high temperature and high humidity is given method. For contaminated samples and workshop air samples, FID detectors should be used, ambient air samples should be used with ECD detectors, and further testing methods should be developed for the early detection of volatile halogenated hydrocarbons in exhaust gases from sources.
