Scope

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