Scope: This document describes atomic fluorescence spectrometry, cold atomic absorption spectrometry and direct sampling methods for the determination of total mercury in feed. This document is applicable to the determination of total mercury in compound feeds, concentrated feeds, concentrate supplements, additive premix feeds, feed ingredients and feed additives. Atomic fluorescence spectrometry: When the sample weight is 0.5g and the constant volume is 50mL, the detection limit of the method is 0.6μg/kg, and the limit of quantification is 3μg/kg. Cold atomic absorption spectrometry: when the sample weight is 2g and the fixed volume is 100 mL, the detection limit of the method is 3 μg/kg, and the limit of quantification is 10 μg/kg. Direct injection method: when the sample weight is 0.1 g, the detection limit of the method is 0.3 μg/kg, and the limit of quantification is 1 μg/kg.
