Abstract:
Objective: To analyze the uncertainty in the determination of formaldehyde in food stimulant.Methods: HPLC with pre-column derivation was used to determine formaldehyde in food stimulant.A calculation formula was established to identify the source of uncertainty and the combined uncertainty was evaluated.Results: The synthetic uncertainty in the determination of formaldehyde was 1.7% and the expanded uncertainty was 3.4%.The formaldehyde content in food stimulant was (1.320 ± 0.044) mg·L-1 (k =2).Conclusion: The study provides reference for the uncertainty analysis on formaldehyde content in food stimulant by HPLC with pre-column derivation.
