分析测试中测量不确定度及评定 第四部分 实例(4):标准溶液配制、标定及稀释的不确定度评定

Uncertainty in measurement and its evaluation in analysis and testing Part 4 Example(4) Evaluation of the uncertainty for preparation, standardization and dilution of standard solution

以配制和稀释钼标准溶液、配制重铬酸钾标准溶液、标定硫酸亚铁铵和高锰酸钾标准溶液为例,讨论了标准溶液的配制、标定和稀释中各种不确定度因素,并评定了各种标准溶液浓度的测量不确定度。

Various factors affecting uncertainty for the preparation, standardization and dilution of standard solution are discussed. Uncertainties of preparation and dilution of molybdenum standard solution, preparation of potassium dichromate and standardization of ferrous ammonium sulfate and potassium premanganate standard solution are evaluated.
