Scope

This Standard specifies the fluorescence spectrophotometry and high-
performance liquid chromatography for the determination of vitamin B2 (namely
riboflavin C17H20N10) in feeds.
Method 1 of this Standard is applicable to the determination of vitamin B2 in
animal and plant feed materials, compound feed and concentrated feed; the
quantitation-limit is 0.25 mg/kg.
Method 2 of this Standard is applicable to the determination of vitamin B2 in
vitamin premix feed, compound premix feed, and concentrated feed. When it is
detected by a fluorescence detector, the quantitation-limit is 5 mg/kg; when it is
detected by an ultraviolet detector, the quantitation-limit is 10 mg/kg.
For the determination of vitamin B2 in concentrated feed, method 1 is the
arbitration method; for the determination of vitamin B2 in vitamin premix feed
and additive premix feed, the high-performance liquid chromatography
fluorescence detector method of method 2 is the arbitration method.
