The analysis of bromate is of particular interest for the assessment of water and food quality due to its toxicity. Analytical instruments such as ion chromatography have been used to measure bromate and require standard solutions for instrument calibration. A measurement method for potassium bromate as the source material of the standard solution has already been established. This paper describes the certification and long-term stability monitoring of bromate ion standard solutions with comprehensive uncertainty evaluations. The stability of potassium iodate is also presented as additional information.
