Scope

This document describes the determination of selenium in feeds by hydride generation-
atomic fluorescence spectrometry, fluorescence spectrophotometry and inductively
coupled plasma-mass spectrometry.
In this document, hydride generation-atomic fluorescence spectrometry and
fluorescence spectrophotometry are applicable to the determination of selenium in
compound feed, concentrated feed, concentrate supplement, additive premix feed and
feed raw materials. Inductively coupled plasma mass spectrometry is applicable to the
determination of selenium in compound feed, concentrated feed, concentrate
supplement and feed raw materials (except mineral feed raw materials).
When the sample size is 1 g and the fixed volume is 50 mL, the detection limit of
hydride generation-atomic fluorescence spectrometry and fluorescence
spectrophotometry is 0.01 mg/kg and the quantification limit is 0.02 mg/kg. When the
sample size is 0.5 g and the fixed volume is 50 mL, the detection limit of inductively
coupled plasma mass spectrometry is 0.01 mg/kg and the quantification limit is 0.02
mg/kg.
