摘　　要：气相色谱-质谱联用法测定化妆品中邻苯二甲酸酯类化合物不确定度的主要来源有标准溶液引入的不确定度、样品引入的不确定度、样品处理过程中引入的不确定度。以邻苯二甲酸丁苄酯(BBP)为例,对各不确定度分量进行了评定,计算了合成不确定度和扩展不确定度。当化妆品中BBP测量结果为10.05 mg/L时,其扩展不确定度为0.70 mg/L(k=2)。The main sources of uncertainty of determination of phthalate esters in cosmetics by gas chromatographymass spectrometry were the standard solution,the sample,the sample handling course. Butyl benzyl phthalate(BBP)as an example,each uncertainty component was evaluated. The combined uncertainty and expanded uncertainty were calculated. As the measuring the results of BBP in cosmetics was 10.05 mg/L,the expanded uncertainty was0.70 mg/L(k=2).
