Choosing the Right Electrode for pH Measurements
Tip: Correct and accurate pH measurements depend upon reliable instruments and electrodes. Selecting the right equipment and procedures for handling and maintenance are crucial for obtaining optimum results and prolonging instrument lifetime.
pH measurement is a very common application in laboratories. However, there are several factors that influence the results, such as different types of pH meters and electrodes, the varying characteristics of a sample to be measured, and the chemical properties of a solution. METTLER TOLEDO has developed “A Guide to pH Measurement – the theory and practice of laboratory pH applications” to provide in-depth information on pH measurement. This comprehensive 55 page document addresses beginners with a basic knowledge as well as professionals who would like to refresh their fundamental knowledge of the subject.
The guide provides a detailed introduction into the basics, history and theory of pH measurement. It then covers the topic of choosing the right electrode for the required application and how to handle electrodes to guarantee optimal functioning. The guidebook furthermore gives troubleshooting advice for pH measurements.
