Uncertainty evaluation for the determination of sucralose in Olives by high performance liquid chromatography
The uncertainty for determination of sucralose in Olives by high performance liquid chromatography with refrac-tive index detector(HPLC-RID)was analyzed from five aspects,including the repeatability of determination,the prepara-tion of standard solution,the pretreatment of sample,fortified recovery rate and others.The fortified recovery rate and the preparation of standard solution has a great influence on the uncertainty according to the evaluation results.The content of sucralose in Olives was(0.025 0±0.001 7)g/kg,k=2.
