See Chinese contents: GB/T 13082-2021 GB/T 13082-2021: Determination of cadmium in feeds
This document describes flame atomic absorption spectrometry and graphite furnace atomic absorption spectrometry, for the determination of cadmium in feed. This document applies to the determination of cadmium, in compound feeds, concentrated feeds, concentrate supplements, additive premixed feeds, feed additives, feed ingredients. In this document, when the sampling amount is 5 g and the constant volume is 50 mL, the detection limit of flame atomic absorption spectrometry is 0.08 mg/kg AND the quantification limit is 0.20 mg/kg. When the sampling amount is 0.5 g and the constant volume is 25 mL, the detection limit of graphite furnace atomic absorption spectrometry is 0.002 mg/kg AND the quantification limit is 0.05 mg/kg.
