Abstract: To base on GB/T10781.8-89, the content of ethyl caproate can be determined with gas chromatography. By the experiment of the uncertainty measurement of the ethyl caproate in Chinese spirits this paper expounded a method to evaluate the uncertainty measurement for inner standard method. At last the combined standard uncertainty and the expanded uncertainty are expressed, which provide the effective and credible quality data to the quality control.

Key words: Chinese spirits, ethyl caproate, uncertainty, gas chromatography, metrology
