中文摘要: 采用气相色谱法测定婴儿配方乳粉中碘的含量，较全面的考虑整个测定过程的不确定度来源并对各不确定度分量进行了评定和量化，计算了合成标准不确定度和扩展不确定度。不确定度主要来自标准物质引入的不确定度。婴儿配方乳粉中碘的含量结果表示为（80.625 6±1.443）g/100 g，k=2。
Abstract:Iodine in formula milk powder was determined by gas chromatography，various factors which could affect the precision of the result were systematically analyzed and the uncertainty of determination result was analysed and quantified.Itwas found that the uncertainty mainly derived from the uncertainty of reference material.The determination resultwas（80.625 6±1.443）g/100 g，k=2.
