GB/T 13079-2006 in English

《GB/T 13079-2006饲料中总砷的测定》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。
本标准规定了饲料中总砷的测定方法。 本标准适用于各种配合饲料、浓缩饲料、添加剂预混合饲料、单一饲料及饲料添加剂。 最低检测浓度：银盐法为0.04 mg/kg；硼氢化物还原光度法为0.04 mg/kg；原子荧光光度法为0.010 mg/kg。

This standard specifies the methods for determination of total arsenic in feeds.
This standard is applicable to formula feed, concentrate feed, feed additive premix, single feed and feed additive.
The minimum detection concentration: for the silver salt method and the borohydride reduction spectrophotometric method, it is 0.04 mg/kg; for atomic fluorescence spectrophotometry, it is 0.010 mg/kg.
