This experiment was based on “Determination of arsenic, cadmium, chromium, lead and the migration of arsenic, cadmium, chromium, nickel, lead, antimony, zinc in food contact materials and products”(GB/T 31604.49-2016), using inductively coupled plasma mass spectrometry Analyzer (ICP-MS) for analysis and detection of antimony migration in food packaging polyethylene terephthalate (PET) samples. The main sources of uncertainty in the test process was analyzed, and it was evaluated the values of standard uncertainty, synthetic uncertainty, and extended uncertainty. And then it was evaluated the applicability of the method by analyzing the results of the uncertainty.
