Scope

本文件描述了饲料中硒测定的氢化物发生原子荧光光谱法、荧光分光光度法和电感耦合等离子体质谱法。本文件中氢化物发生原子荧光光谱法、荧光分光光度法适用于配合饲料、浓缩饲料、精料补充料、添加剂预混合饲料和饲料原料中硒的测定，电感耦合等离子体质谱法适用于配合饲料、浓缩饲料、精料补充料和饲料原料（矿物质饲料原料除外）中硒的测定。当取样量为1 g、定容体积为50 mL时，氢化物发生原子荧光光谱法、荧光分光光度法的检出限为0.01 mg/kg、定量限为0.02 mg/kg；当取样量为0.5 g、定容体积为50 mL时，电感耦合等离子体质谱法的检出限为0.01 mg/kg、定量限为0.02 mg/kg。
