GB/T 21311-2007 in English

《GB/T 21311-2007动物源性食品中硝基呋喃类药物代谢物残留量检测方法 高效液相色谱/串联质谱法》由424-caiq（中国检验检疫科学研究院）归口，主管部门为国家市场监督管理总局。
本标准规定了动物源性食品中硝基呋喃类药物代谢物3-氨基-2恶唑酮（3-amino-2-oxalidinone,AOZ）、5-吗啉甲基-3-氨 基-2-氨 基-2-恶唑烷基酮（5-morpholinomethyl-3-amino-2-oxalidinone,AMOZ）、1-氨基-乙内酰脲（1-amino-hydantoin,AHD）和氨基脲（semicarbazide,SEM）残留量的高效液相色谱/串联质谱测定方法。
本标准适用于肌肉、内脏、鱼、虾、蛋、奶、蜂蜜和肠衣中硝基呋喃类药物代谢物3-氨基-2-恶唑酮、5-吗啉甲基-3-氨基-2-恶唑烷基酮、1-氨基-乙内酰脲和氨基脲残留量的定性确证和定量测定。

This standard specifies the HPLC-MS/MS determination method for residues of nitrofuran metabolites like 3-amino-2-oxalidinone (AOZ)), 5-morpholinomethyl-3-amino-2-oxalidinone (AMOZ), 1-amino-hydantoin (AHD) and semicarbazide (SEM) in foodstuffs of animal origin.
This standard is applicable to the qualitative determination and quantitative determination for residues of nitrofuran metabolites like 3-amino-2-oxalidinone, 5-morpholinomethyl-3-amino-2-oxalidinone, 1-amino-hydantoin and semicarbazide in muscle, viscera, fish, shrimp, egg, milk, honey and sausage skin.
