GB/T 28722-2012 《Determination of iron and lead in amino acids - Atomic absorption spectrometry》 Related products

This standard specifies methods for the determination of iron and lead in amino acids using atomic absorption spectroscopy (AAS). The standard applies to the measurement of iron and lead by graphite furnace and flame atomic absorption spectroscopy (AAS). The detection limit for lead by graphite furnace method is 0.005 mg/kg, the detection limit for lead by flame method is 0.1 mg/kg, and the detection limit for iron is 2 mg/kg. The standard details methods for sample handling, instrument operation, reagent use, and result calculation to ensure accurate determination of iron and lead content in amino acids.
