Abstract
In accordance with atomic fluorescence spectrophotometry of Selenium in food,the main sources of measure of uncertainty were analyzed,such as the standard curve uncertainty,sample pretreatment uncertainty and determination repeatability uncertainty.The synthetic uncertainty was 0.15μg/kg and the expansion uncertainty was 0.3μg/kg.
