This document describes the silver salt method, hydride generation-atomic fluorescence spectrometry and inductively coupled plasma mass spectrometry for the determination of total arsenic in feeds. This document is applicable to the determination of total arsenic in compound feeds, concentrated feeds, concentrate supplements, additive premixed feeds, feedstuffs and feed additives. When the sampling size is 5 g and the constant volume is 50 mL, the detection limit of the silver salt method is 0.25 mg/kg and the quantitation limit is 0.50 mg/kg; when the sampling size is 5 g, the constant volume is 50 mL and the dilution factor is 20, the detection limit of the hydride generation-atomic fluorescence spectrometry and inductively coupled plasma mass spectrometry is 0.02 mg/kg, and the quantitation limit is 0.05 mg/kg.
