摘要
文章依据《化学分析中不确定度的评估指南》,从盐产品中氯离子含量检验的技术规定,识别不确定度的来源,不确定度分量的定量,计算合成标准不确定度,计算扩展不确定度等几个方面,详细阐述了盐产品中氯离子检验过程测量不确定度的评估方法,得出了氯离子检验过程中玻璃量器的体积分量对其测量不确定度贡献最大的结论。
Based on the Guidance on Evaluating the Uncertainty in Chemical Analysis, the evaluation of uncertainty in the measurement of chloride ion content in salt products are discussed in detail for the aspects of technical requirements for measurement of chloride ion, identifying the sources of uncertainty, quantifying the components of uncertainty, calculating the total standard uncertainty and expanded uncertainty, etc. The conclusion was that the volume component of working glass containers made the greatest contributions to the uncertainty in the measurement of chloride ion content.
