《GB/T 17812-2008饲料中维生素E的测定 高效液相色谱法》由TC76(全国饲料工业标准化技术委员会)归口,主管部门为国家标准化管理委员会。
本标准代替GB/T 17812-1999《饲料中维生素E的测定 高效液相色谱法》。
本标准规定了饲料中维生素E的测定――高效液相色谱法。
本标准第一法适用于配合饲料、浓缩饲料、复合预混合饲料、维生素预混合饲料中维生素E的测定。
本标准与GB/T 17812-1999相比主要变化如下:
――原标准方法为第一法皂化提取法(仲裁法);
――补充第二法直接提取法(快速法),适用于维生素预混料中维生素E的测定。


Scope

This standard specifies the determination of vitamin E in feed - high performance liquid chromatography. The first method of this standard is applicable to the determination of vitamin E (dl—a-tocopherol) in compound feed, concentrated feed, compound premixed feed, and vitamin premixed feed, with a quantitative limit of 1 mg/kg. The second method of this standard is applicable to the determination of vitamin E (dl-a-tocopheryl acetate) in vitamin premixed feed, and the limit of quantification is 20 mg/kg.
