摘要
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。
The paper discusses the difference in inspection device, inspection scope and target compounds of analysis methods between at home and abroad using gas chromatographic to determine volatile halogenated hy- drocarbons in gas sampling. The sampling methods of pollution sources under high temperature and high humid- ity conditions are given. FID detector is suitble for contaminated samples. ECD detector is suitble for ambient air samples. The standard testing method of volatile halogenated hydrocarbons in exhaust source should be en- acted as soon as oossible.
