白酒中总酯不确定度评估研究

Study on Uncertainty Evaluation of Total Esters in Spirits

分析了白酒中总酯检测含量方法,确定了各个不确定度分量值,得出白酒中总酯含量的测定结果的不确定度主要来源于玻璃仪器、标准滴定溶液等因素,其余部分所占比例较小,在实际检测评定中可以予以忽略。最终得出白酒中总酯测定的扩展不确定度。为实验室在该项目进一步提高检测数据的可靠性和一致性做参考。

Analysis of the content of total esters in liquor detection method to determine each uncertainty component value determination results of total ester content in liquor of the uncertainty mainly comes fromthe glass instrument,standard solution and other factors,the rest of the proportion of small,can be ignored in actual detection and evaluation.Finally in liquor determination of the total esters extended uncertainty.For the laboratory in the project to further improve the detection reliability and consistency of data for reference.
