GB/T 20380.1-2006 Focus on the determination of arsenic content in starch and its products. The standard adopts atomic absorption spectroscopy (AAS) method, detailing the sample pretreatment steps to convert the arsenic in starch products into a detectable state. The absorption degree of arsenic atoms to specific wavelengths of light is accurately determined by instruments, and the arsenic content is calculated according to the standard Linear dispersion. The determination process strictly regulates the operation process, instrument calibrating and data processing methods. The standard provides a key means to ensure the mass safety of starch and its products, and can effectively monitor arsenic pollution. It is widely used in food production, mass detection and other fields.
