摘要
以测定样品中海洛因的含量为例,评定了气相色谱法测定结果的不确定度。建立数学模型,分析各不确定度分量,将不确定度分量合成,并计算其测定结果的扩展不确定度。
The uncertainty of measurement for heroin content in a sample by GC was evaluated.The mathematical model of measurement was set up.The different parts of uncertainty were analyzed,and the combined standard uncertainty and the expanded uncertainty of measurement results were calculated.
