Scope

This Standard specifies two methods for the determination of chromium content in feed
by atomic absorption spectrometer and spectrophotometer.
Method 1 of this Standard is atomic absorption spectrometry. It is applicable to feed
raw materials (including leather powder for feed, hydrolyzed leather powder), trace
element premixes, compound premixes, concentrates and compound feeds. The
minimum detection limit of graphite furnace atomic absorption spectrometry is 0.005
μg/kg. The minimum detection limit of flame atomic absorption spectrometry is 150
μg/kg. Method 2 of this Standard is spectrophotometric method. It is applicable to the
determination of chromium in feed raw materials (including hydrolyzed leather powder)
and compound feed.

Summary	This standard specifies the use of two atomic absorption spectroscopy and chromium content in feed spectrophotometer. This standard method of atomic absorption spectrometry. Applicable to feed materials (including leather powder feed, hydrolyzed leather meal), trace element premix, premix, concentrates and feed, in which the graphite furnace atomic absorption spectrometry detection limit was 0. 005��g/kg, flame atomic absorption spectrometry detection limit was 150��g/kg. This standard method for the spectrophotometric method. Applicable to feed materials (including leather hydrolyzed flour) and with the determination of chromium in the feed.
