针对固定污染源排放烟气的特点,采用气相色谱-火焰离子化检测法、光离子化检测法,气相色谱-质谱GC-MS对烟气中的挥发性有机物进行现场比对测试.测试结果表明:光离子化检测法与其他测试方法测试结果差异较大,气相色谱-火焰离子化检测法和气相色谱-质谱GC-MS结果差异较小,适用于固定污染源废气中挥发性有机物的测试.并根据监测结果提出建议.%For fixed pollution source emission characteristics of flue gas,gas chromatography-flame ionization method,optical ionization method,gas chromatography-mass spectrometry (GC-MS on the volatile organic compounds in the smoke test on site were used to detect Volatile Organic Compounds.Test results showed that the test differences of the optical ionization method is larger than other test methods,the test differences of the gas chromatography flame ionization method and gas chromatography-mass spectrometry (GC-MS result difference is smaller than other methods,they are suitable for the test of volatile organic compounds of stationary sources emissions.And according to the monitoring results,the suggestion is also proposed.
