| Abstract: | The sources of uncertainty in high performance liquid chromatography (HPLC) determination of sorbic acid in
wine were fully analyzed according to the mathematical model. The uncertainties were mainly attributed to the calibration of
measuring tools used in the preparation of standard curve, and the repeated experiments in the determination. The content of
sorbic acid in wine could be shown as (70.4 ± 2.7) mg/kg (k = 2). |
