摘    要:为了检定气相色谱仪数据的准确性,要考虑检定不确定度的影响.通过对气相色谱仪热导检测器(TCD)灵敏度进行校准过程中引入的不确定度分量进行了评定.TCD灵敏度的相对不确定度为2.1%,扩展不确定度为4.2%(k=2),所有检定项目中,标准样品进样量的不确定度是最大的.此方法简单、实用,可用于带色谱工作站的GC的校准.

关 键 词:气相色谱法  灵敏度  不确定度

Abstract:For evaluating the accuracy of data from gas chromatography,the influence about uncertainty will be considered. The uncertainty of the detector TCD sensitivity of gas chromatography is evaluated in the process of calibrating the detector TCD sensitivity. The relative uncertainty is 2.1% and the relative expanded uncertainty is 4.2%(k=2). Among all the evaluating items,the uncertainty about injection volume of standard sample is the greatest. This method is simple and practical,which is applicable for calibr...
Keywords:gas chromatography  sensitivity  uncertainty
