Determination of the Impurities in Pesticide Phorate by GC/ MS
摘要/Abstract
摘要：
应用毛细管气相色谱和质谱法对杀虫剂甲拌磷原油进行了很好的分离和分析,通过MSLS质谱数据检索系统对多数杂质进行了定性.讨论了甲拌磷及两种硫代磷酸酯的质谱特性,并通过质谱解析对主要碎片和裂解机理加以证实
Abstract：
Primary oil of pesticide phorate has been separated well and analyzed by capillary gas chromatography/mass spectrometry. With the MSLS(Mass Spectrum Data Index System),major impurities are qualitatively determined.The mass spectrometric characteristics of phorate and two phosphorothioates are discussed and the chief fragments and fragmentation mechanism are identified with the interpretation of mass spectrum.
