Objective To evaluate the uncertainty of determination of glucose in mushroom by ion chromatography. Methods According to JJF 1059.1-2012 Measurement uncertainty evaluation and presentation, the uncertainty of main factors such as weighing, standard solution preparation, standard curve fitting and recovery were investigated, and the components of uncertainty were calculated and synthesized. Results When the content of glucose in mushroom was 3.29 μg/kg, the extended uncertainty was 0.30 μg/kg (k=2) under the 95% confidence interval. The evaluation results showed that the uncertainties of the experiment were mainly derived from curves calibration and recovery rates. Conclusion The evaluation method is accurate and reliable, which is suitable for the evaluation of uncertainty of determination of glucose in mushroom by ion chromatography. It has guiding significance to improve the accuracy of test results.
