Measurement of pH is carried out for a variety of purposes:
- to test a sample against a legal requirement;
- to test a chemical against a specification as part of an analytical method;
- monitoring and controlling biochemical and physiological reactions;
- process control in the chemical industry.
Each of the above examples requires a particular accuracy and precision. Using modern equipment such measurements can be made very easily. However, it is not always easy to obtain reliable results. This guide covers the basic principles underlying the measurement of pH. It provides guidance to an inexperienced analyst on choice and use of equipment and ways of ensuring that uncertainties are kept to a minimum..
Topics covered include:
- Buffer materials with reference pH values
- pH meters
- pH electrodes
- Care of electrodes
- Selection of elctrodes
- Uncertainty of pH measurements
- Practical exercises to evaluate competence.
