分析了气相色谱法检测白酒中乙酸乙酯含量，确定了各个不确定度分量值，得出白酒中乙酸乙酯含量的测定结果的不确定度主要来源于标准溶液、气相色谱仪及重复性检验等因素。其余部分占的比例较小，在实际检测评定中可以予以忽略。最终得出白酒中乙酸乙酯测定的扩展不确定度。为实验室在该项目检测过程中进一步提高检测数据的可靠性和一致性作参考。
分析瞭氣相色譜法檢測白酒中乙痠乙酯含量，確定瞭各箇不確定度分量值，得齣白酒中乙痠乙酯含量的測定結果的不確定度主要來源于標準溶液、氣相色譜儀及重複性檢驗等因素。其餘部分佔的比例較小，在實際檢測評定中可以予以忽略。最終得齣白酒中乙痠乙酯測定的擴展不確定度。為實驗室在該項目檢測過程中進一步提高檢測數據的可靠性和一緻性作參攷。

The detection of ethyl acetate content in liquor by gas chromatography ( GC ) was analyzed, and each uncertainty component value was identified. The uncertainty of this experiment was mainly from the standard solution, GC and repeatability, etc. The rest of the proportion of small can be ignored in the actual detection evaluation. Finally, the extended uncertainty of determination of ethyl acetate in liquor was obtained. As a reference to laboratory in the detection of ethyl acetate by GC, the reliability and consistency of the test data was improved.
