GB/T 13080-2018 Translated English of Chinese Standard (GB/T 13080-2018, GBT13080-2018)

This Standard specifies flame atomic absorption spectrometry and graphite furnace atomic absorption spectrometry for the determination of lead in feeds. This Standard is applicable to the determination of lead in compound feeds, concentrated feeds, additive premix feeds, concentrate supplement and feed raw materials. When the sampling volume is 5 g and the constant volume is 50 mL, the quantification limit for flame atomic absorption spectrometry is 2 mg/kg. When the sampling volume is 1 g and the constant volume is 10 mL, the quantification limit for graphite furnace atomic absorption spectrometry is 100 ¦Ìg/kg.
