采用气相色谱-质谱法(GC-MS)研究了不同溶剂对有机氯农药测定的影响。结果表明,有机氯农药在不同溶剂中的GC-MS响应值是有差异的,但保留时间不变,且随着有机氯农药质量浓度的增加,这种溶剂效应对大部分有机氯农药的作用减弱。经分析溶剂的极性对有机氯农药测定有显著的影响。
The effects of different solvents on the response of organochlorine pesticides were studied by gas chromatography mass spectrometry (GC-MS). The results showed that the different solvents had obvious effects on gas chormatographic responses in the determination of organochlorine pesticide, however, the retention time didnt change. With the concentration of organochlorine pesticides increasing, the solvent effects on some organochlorine pesticides reduced. And the polarity of the injection solvents had obvious effects on gas chormatographic responses in the determination of organochlorine pesticide.
