摘要:
目前已有几种比较成熟的三聚氰胺检测方法,其中牛奶中三聚氰胺的气质检测方法(GB/T 22388-2008)上机耗时较长,且质谱图不太理想。与饲料中三聚氰胺的气质检测条件进行比较,发现按照饲料中三聚氰胺气质方法(NY/T 1372-2007)改变质谱条件中的升温程序后,质谱图更为理想,回收率可达85%,说明牛奶中三聚氰胺的检测沿用饲料中三聚氰胺的气质条件更快捷、更理想。
关键词: 牛奶;三聚氰胺;气质检测
Abstract:
Some methods for determining melamine had been quite mature. But it takes too much time to analyze melamine in milk (GB/T 22388-2008) by using GC-MS method, and the mass spectrum chart is not good enough. Comparing with determination method of melamine in feed, the author finds that if we change the condition of programming temperature according to the method in feed (NY/T 1372-2007), the mass spectrum chart has been better, and at the same time the recovery might reach up to 85%. That means the GC-MS condition which used to analyze melamine in feed is also suitable to analyze melamine in milk.
Key words: milk, melamine, determination by GC-MS method
