Abstract
This paper was based on the method and principle of uncertainty evaluation,through the example of determination of industrial triethanolamines by gas chromatography,the source of uncertainty was established.Some factors influencing the uncertainty of the test results of industrial triethanolamine’s content were discussed.The components of related standard uncertainty,combined standard uncertainty,and expanded uncertainty were calculated.The results showed that evaluation of uncertainty for determination of industrial triethanolamine’s content by gas chromatography was mainly due to measurement repeatability and instrument calibration.
