Comparable pH Measurements by Metrological Traceability
After the completion of “The Measurement of pH. Definitions,
Standards, and Procedures (IUPAC Recommendations 2002),”
2169–2200 (2002), a workshop on the “Importance
of Traceable pH Measurements in Science and Technology”
was held at PTB/Braunschweig, Germany, in September 2001.
The workshop, which was organized and promoted by members
of this project’s task group, attracted a wide range
of participants and revealed priorities and strong interest
from the concerned community for continuing action. The meeting
set the following objectives:
- to implement traceability chains for pH values in routine measurements in order to achieve target uncertainties for specific applications
- to develop educational and quality control tools for reference and testing laboratories under the observation of chemical and metrological principles
- to improve the comparability and the assessment of pH values
The project, which has the support of the Analytical Chemistry Division, the Physical and Biophysical Division, the Chemistry and Environment Division, and the Committee on Chemistry and Industry, is scheduled to take three years and will be carried out in two parts pertaining to pH measurements in complex matrices:
- Part I—pH Measurements in water quality monitoring and assessment
- Part II—pH Measurements of clinical, biochemical, and environmental relevance
The task group consists of worldwide experts in the field, which aims to impact the scientific community due to both the relevance of the subject and the multiple scientific aspects involved in pH measurement and assessment.
