【原创】已经亲自测定了某奶粉中的三聚氰胺，参考FDA方法（已追贴结果）

Laboratory Information Bulletin LIB No. 4396 Volume 23, May 2007Determination of Melamine Residues in Catfish Tissue by Triple Quadrupole LC-MS-MS with HILIC ChromatographyWendy C. Andersen, Sherri B. Turnipseed, Christine M. Karbiwnyk, and Mark R. MadsonU.S. Food and Drug Administration, Animal Drugs Research Center, Denver, CO
ABSTRACTA triple quadrupole liquid chromatography tandem mass spectrometry method is presented for the quantitative determination and confirmation of melamine residues in catfish. Catfish tissue was extracted with 50:50 acetonitrile:water and 1 N hydrochloric acid and cleaned-up using Oasis® MCX solid phase extraction cartridges. Extracts were analyzed by LC-MS-MS with HILIC chromatography and electrospray ionization in positive ion mode. The precursor ion for melamine is m/z 127. Two product ion transitions were monitored at m/z 85 and 68 for quantification and confirmation. Catfish tissue was fortified at 10, 25, 50, 100, and 500 ng/g (ppb). The average recovery of melamine from fortified samples (n = 17) was 76.3 % with an RSD of 14.3 %.

效果跟原方法差不多哦，楼主在哪里的？可以接受委托检测不？

国家已经发布了三聚氰胺的检测方法，大家可以找找

国家已经发布了三聚氰胺的检测方法 ，谁能提供

hoho牛人啊

FDA方法已经下载，多谢分享！

期待楼主更多的实践

我也想要国家标准

楼主厉害呀,期待公布内标检测结果

lz厉害，我也想要标准。
