| Abstract: | According to the principle and procedure of JJF1059—1999 Evaluation and Expression of Uncertainty in
Measurement, a mathematical mode was established for uncertainty evaluation for HPLC determination of natamycin in
dairy products. Sources of uncertainty in the entire measurement process were analyzed and each component of uncertainty
was evaluated and synthesized. The synthetic standard uncertainty was 0.014, and the expanded uncertainty was 0.28 mg/kg.
The confidence interval for natamycin determination was (9.95 ± 0.28) mg/kg, k = 2. |
