Abstract
Gas Chromatography-Mass Spectrometry(GC-MS)plays a crucial role in the detection of Volatile Organic Compounds(VOCs)in waste gas,which can efficiently separate and detect multiple VOCs in complex exhaust gases,supporting environmental monitoring and pollution control.In response to the challenges of multiple types of VOCs,large concentration differences,and matrix interference,the experiment significantly improves separation efficiency and detection sensitivity by optimizing chromatographic column selection,initial temperature,heating program,and mass spectrometry conditions.The experimental results show that this method has low detection limit,high precision,and accuracy,and can simultaneously detect various VOCs such as benzene derivatives,halogenated hydrocarbons,alcohols,and ketones.Future research will expand its application scope and combine intelligent technology to promote real-time and accurate monitoring of VOCs,helping to continuously improve environmental quality.关键词
