Abstract:
This study aimed to assess the measurement uncertainty of a new method for determination of allura redin food by high performance liquid chromatography (HPLC).The uncertainty of mathematical model of allura red is based on Europe for Analytical Chemistry(EURACHEM) guidelines.The sources and components of uncertainty were calculated,including recovery,working solution,sample mass,final volume,response of standard solution,response of sample solution.The expanded uncertainty was 0.0024 (k=2).Uncertainty of working solution was the most significant factor contributing to the total uncertainty,accounting for 86.2％.The uncertainty of volume accounted for the minimum at 0.025％.The developed method is simple and accurate,which can be used for the determination of allura redin puffed samples.
