Abstract: In order to ensure the accuracy and reliability of the test data, it is necessary to evaluate the uncertainty of ion chromatography. Using the uncertainty evaluation methods, this paper analyzes and quantifies the main uncertainty sources of trace sodium in the power plant water and steam system measured by ion chromatography. The outcome of the uncertainty evaluation indicates that the uncertainty in the trace sodium measurement mainly results from the standard curve fitting. Other affecting factors include the repeatability, recovery and preparation of the standard solution.

Key words: ion chromatography, uncertainty, power plant, water and steam system, sodium
