line-level: 2">Application of Gas Chromatography-Mass Spectrometry in Groundwater Analysis
The organic pollutants of α-HCH,β-HCH,γ-HCH,δ-HCH,p,p’-DDE,p,p’-DDD,o,p’-DDT,p,p’-DDT,hexachlorobenzene,benzopyrene in groundwater samples were quantitatively determined by gas chromatography (GC) and high performance liquid chromatography (HPLC). And gas chromatography-mass spectrometry (GC-MS) was also used for the identification of organic pollutants in the samples with complex matrix. The analytical results indicate that GC-MS plays a very important role in analysis of organic pollutants in groundwater samples.
