GB/T 20380.4-2006 Determination of cadmium content in starch and its products by electrothermal atomic absorption spectroscopy (AAS). For various starches and related products, the standard specifies the sample collection and processing methods to convert the cadmium element into a detectable state. With the help of electrothermal devices to make cadmium atomization, the absorption of cadmium atoms to specific wavelengths of light is measured by Light spectrum instrument, and the cadmium content is accurately calculated according to the standard Linear dispersion. The whole process of measurement is strictly regulated on instrument operation, environmental conditions and data recording processing, providing a reliable means for monitoring cadmium pollution of starch products, and effectively ensuring food safety and product mass.
