| Abstract: | [ Objective ] To assess the uncertainty in measurement of folic acid in health food by HPLC. [ Method ] The uncertainty was evaluated with the establishment of mathematical model and the analysis of various factors affecting sample detection. [ Result] The combined uncertainty was then finally obtained by synthesizing the uncertainties of various component variables ： （ 33.0 ± 1.7 ） g/kg （ K = 2 ）. [ Conclusion ] The main sources of uncertainty were confirmed and reliable theoretical basis could be supplied for the effective control for the determination of folic acid by this method. |
