GB/T 14609-2008 Inspection of grain and oils—Determination of copper,iron,manganese,zinc,calcium,magnesium in cereals and derived products by atomic absorption and flame spectrophotometry

Scope

This standard specifies the principles, reagents, instruments and equipment, analytical procedures, result calculation, and repeatability for determining copper, iron, manganese, zinc, calcium, and magnesium in grains and their products by flame atomic absorption spectrometry.
This standard is applicable to the determination of elements such as copper, iron, manganese, zinc, calcium, and magnesium in grains and their products.
The detection limits of this method are: copper 0.6 mg/kg, iron 2.4 mg/kg, manganese 0.5 mg/kg, zinc 0.4 mg/kg, calcium 1.5 mg/kg, and magnesium 0.7 mg/kg.
