This standard specifies the method for the determination of calcium in feed by atomic absorption spectrometry. This standard is applicable to the determination of calcium in feed and is not applicable to mineral feed. The quantitative determination range of this standard is 0.2 mg/L ~ 5.0 mg/L. When the sample volume is 1g and the constant volume is 50mL, the detection limit of this standard method is 2.5mg/kg.
