同位素稀释质谱法测定鸡蛋中的三聚氰胺
Determination of Melamine in Egg by GC-IDMS
-
Abstract: The gas chromatograph-isotope dilution mass spectrometry method was presented for determination of melamine in egg. The sample was extracted by acetonitrile/water and derivatized at 70 ℃ for 1 h, then analyzed by GC-IDMS with VF-5 column. The detection limit is 1.5 ng•g－1, and the recovery is 96.6%. This method is sensitive, accurate and suitable to determine melamine in egg.
