| Abstract: | The determination of iron in wine adopts the first method of GB 5009.90-2016 《National Food Safety Standard Determination of Iron in Food》flame atomic absorption spectrometry-microwave digestion method, and the mathematical model is used to evaluate and calculate the uncertainty of the results. The uncertainty of each component of standard solution preparation, measurement repeatability and instrument stability is analyzed, and the uncertainty of each component and the synthesis uncertainty are obtained, and finally a more objective result is obtained. |
