Scope

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 μg/kg.
