摘要
为了提高测定结果的准确度,通过建立气相色谱质谱联用法测定饲料中雌酮的测量不确定度分析的数学模型,对测量过程中的不确定度来源进行逐项分析和合成,最终得出气质联用法测定饲料中雌酮的不确定度结果。结果表明:雌酮的扩展不确定度为0.27g·kg-1。此方法可用于气相色谱质谱联用法测定饲料中雌酮的测量不确定度分析,使测定结果更加可靠。
In order to improve the accuracy of determination results,the mathematical model to estimate the uncertainty of Gas Chromatography-mass Sepectrometry in measuring of estrone in feed had been constructed.Furthermore,by termwise analyzing and synthesizing the sources,which caused uncertainty in the measuring process,results of the measurement uncertainty of GC/MS in measuring the estrone in feed had been put forward.The results showed that uncertainty for estrone was 0.27g·kg-1.The established mathematic model was reasonable and relible,it was applicable to the uncertainty analysis of Gas Chromatography-mass Sepectrometry in measuring of estrone in feed.
