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.
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.

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.
Food and drinks are a crucial part of everyday life. In order to ensure the maximum safety and regulatory requirements correct testing is paramount. Here are a number of application guides for food and drink samples that each require a specific electrode or method to measure accurately and precisely.
pH meters come with a variety of settings and applications, along with the need to calibrate on a regular basis. This page can guide you through this process along with any additional needs like installation and PC connections.
