高效液相色谱法测定化妆品中甲基氯异噻唑啉酮的不确定度分析

Analysis of Uncertainty in Determination of 5-Chloro-2-methyl-4-isothiazolin-3-one in Cosmetic

本文对高效液相色谱法测定化妆品中甲基氯异噻唑啉酮含量进行了不确定度分析,计算出样品含量为0.000991%时的合成不确定度和扩展不确定度。

The uncertainty of determination of 5-Chloro-2-methyl-4-isothiazolin-3-one in cosmetic using high performance liquid chromatography was analyzed in this paper. When the 5-Chloro-2-methyl-4-isothiazolin-3-one content in the sample was 0.000991%,the combined uncertainty and extended uncertainty were calculated.
