日前,贵州省烟草专卖局一项发明专利“一种测定烟叶中202种农药残留量的方法”获得国家知识产权局授权。此项发明针对全球烟草中正在或潜在使用的202种化学农药,应用“简便、快速、安全、价格低廉”(即QuEchERS法)快速提取烟末中多种农药残留量,用“程序升温汽化-气相色谱-三重四极杆串联质谱仪(PTV-GC-MS/MS)”测定其残留量。同时,经过大量的检测条件优化,建立了202种农残共221个组分的保留时间、母离子/子离子对、碰撞能量等质谱参数数据库。该方法具有干扰少、农药品种覆盖面广,前处
Recently, an invention patent of Guizhou Provincial Tobacco Monopoly Bureau, “A Method for Determining 202 Pesticide Residues in Tobacco Leaves,” was authorized by the State Intellectual Property Office. This invention is directed against 202 kinds of chemical pesticides currently being used in the world or potential applications, and the rapid extraction of various pesticide residues in tobacco smoke by using “simple, fast, safe, inexpensive” (ie QuEchERS method) Determination of residuals by temperature-controlled vaporization-gas chromatography-triple quadrupole tandem mass spectrometry (PTV-GC-MS / MS). At the same time, after a large number of testing conditions were optimized, a total of 221 kinds of pesticide residues of 221 components of retention time, precursor / ion pair, collision energy and other mass spectrometry parameters database. The method has less interference, wide coverage of pesticide varieties, before
