General description
The pH buffer standards are measured and qualified using differential potentiometry with two platinum hydrogen electrodes. This method allows the comparison of the reference buffers to the corresponding primary reference materials by PTB (Physical Technical Institute, Germany) and NIST (National Institute of Standards and Technology, USA). Uncertainty data and traceability are documented in a comprehensive, batch-specific Certificate of Analysis.
