Key comparison on Borate Buffer
Project Description
The comparison is a subsequent comparison of the CCQM-K19.2018 and is organised mainly for European institutes that either could not participate in the CCQM-K19.2018 or could not provide the results due to complications related to the corona pandemics in 2021. The comparison aims to demonstrate the capability of the participating institutes to measure pH of borate buffer (pH~9.2) at 15 °C, 25 °C and 37 °C, optionally at 5 °C and 50 °C. The participating institutes may use a method of their choice but it is expected that the method of highest available level will be used.
The supporting laboratory for this project is SMU (Slovakia).
