摘要
文中根据QB/T 1692.4-2010标准,通过对卫生香中甲醛含量测量结果不确定度的研究,系统分析乙酰丙酮分光光度法测定卫生香甲醛含量不确定度的来源,并对各个不确定度分量进行量化,且进行合成不确定度评定。结果表明:卫生香甲醛含量测定的不确定度主要来自于标准曲线引入的相对不确定度分量,即甲醛标准溶液的配置和标准曲线的拟合。
Based on standard QB/T 1692.4-2010,through the study of the uncertainty of the measurement results of formaldehyde content in health incense,this paper systematically analyzes the sources of uncertainty in the determination of formaldehyde in incense by acetylacetone Spectrophotometry,quantifies each uncertainty component,and evaluates the combined uncertainty.The results showed that the uncertainty of formaldehyde content in health incense mainly cames from the relative uncertainty component introduced by the standard curve,that is,the configuration of formaldehyde standard solution and the fitting of standard curve.
