Scope

This document specifies the method that uses atomic absorption spectrometry to
determine the contents of calcium (Ca), copper (Cu), iron (Fe), magnesium (Mg),
manganese (Mn), potassium (K), sodium (Na) and zinc (Zn) in feeds.
This Standard is applicable to the determination of the contents of calcium (Ca), copper
(Cu), iron (Fe), magnesium (Mg), manganese (Mn), potassium (K), sodium (Na) and
zinc (Zn) in compound feeds, concentrate feeds, concentrate supplements, additive
premixes and feed ingredients.
The detection limit of each element content of this method is:
K, Na: 500mg/kg;
Ca, Mg: 50mg/kg;
Cu, Fe, Mn, Zn: 5mg/kg.
