pH Applications and Electrodes

The electrode is the key to successful analysis. Since the electrode is the only part of the analytical instrument that is in direct contact with the sample, its selection and maintenance have the strongest influence on precise and accurate measurements. However, a pH electrode that has been correctly selected and that has been working properly may nevertheless suddenly start performing badly. Below are guides to help you chose the right electrode for each application.

The Perfect InLab™ pH Electrode Handling

Electrodes are one of the most important parts of the any pH measuring system. In order to ensure you have the most accurate and precise results extra care need to be taken over the unpacking, storage, cleaning and maintenance. Below are some videos to guide you through this process.

How to Measure PH in Samples Containing TRIS and Biological Samples

TRIS buffers, which are often present in biological samples can cause challenges in pH measurement. The interaction between classic electrolyte solutions and the key components of the TRIS base leads to junction blockage and shortened sensor lifespan. Selection of the appropriate reference system can allow improved sensor accuracy and extended lifetime. Measuring pH in protein-containing samples can be challenging as protein can foul both the pH sensing glass and classical ceramic junctions. In order to obtain accurate pH readings, both of those components must be maintained in optimal condition.
