中文摘要:

对高效液相色谱法测定烟草薄涂布液片中苯甲酸含量的测量不确定度进行评定。建立数学模型,分析不确定度来源。

英文摘要:

This manuscript study the measurement uncertainty during the determination of benzoic acid in the reconstituted tobacco sheets by high performance liquid chromatography(HPLC).For this,a mathematic model was established and the source of the uncertainty was analyzed.Each components of uncertainty was estimated by analyzing the various variable parameters among the procedures,the combined uncertainty was then finally determined by synthesizing the uncertainties of various component variables.The results showed the mathematic model was reasonable and reliable.
