| Abstract: | 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. |
