Electroanalytical techniques use electrical quantities such as charge, current, or potential and measure their relations with chemical parameters. This field involves studying chemical reaction ...

Although the known photometric techniques for the calculation of ammonia are accurate, they take up a substantial amount of time (Nessler technique 30 min, indophenol technique 90 min reaction time).

Each year, lab technicians use ion-selective electrodes (ISEs) to make more than 1 billion measurements of ion concentrations in biological and environmental samples, according to industry estimates.
