Uncertainty evaluation for the determination of benzoic acid in milk powder by HPLC

Yongping Huang

Abstract

Based on JJF1059-1999 Evaluation of the Uncertainty of Determination and Expression,a mathematical model was established to assess the uncertainty of analyzing benzoic acid in milk powder by HPLC.Factors that were contributing to the uncertainty were analyzed,quantified and synthesized.The results showed that the uncertainty of this experiment is mainly caused by the treatment of sample.
