Abstract
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.
期刊介绍：
Accreditation and Quality Assurance has established itself as the leading information and discussion forum for all aspects relevant to quality, transparency and reliability of measurement results in chemical and biological sciences. The journal serves the information needs of researchers, practitioners and decision makers dealing with quality assurance and quality management, including the development and application of metrological principles and concepts such as traceability or measurement uncertainty in the following fields: environment, nutrition, consumer protection, geology, metallurgy, pharmacy, forensics, clinical chemistry and laboratory medicine, and microbiology.
