Electrode Ion Sensitive refers to a type of electrode that is designed to measure the concentration of specific ions in a solution. However, there are several synonyms that can also be used to describe this type of electrode. Firstly, it can be referred to as an Ion-Selective Electrode, as it selectively responds to a specific ion of interest. Additionally, it can be called an Ion-Sensitive Field Effect Transistor (ISFET), as it operates based on the electrical properties of a semiconductor. Another synonym is Ion-Selective Field Effect Transistor (ISFET), which is similar to an ISFET but specifically designed for ion selectivity. Lastly, it can be referred to as an Ion-Selective Membrane Electrode, since it often contains a membrane that selectively interacts with specific ions.
