Ion selective electrodeThe characteristics are:

① It measures the activity of specific ions in the solution rather than the total concentration;

② Easy and fast to use, with a wide range of applications, especially suitable for the determination of alkali metals, nitrate ions, etc;

③ Not affected by the color or turbidity of the test solution, it is particularly suitable for continuous automatic monitoring and on-site analysis of water quality. At present, the ion selective electrode method used for the determination of pH and fluoride ions has been established as the standard method. In the automatic continuous monitoring system for water quality, more than 10 projects use the ion selective electrode method.

Ion selective electrodeApplication:

Ion selective electrode is a simple, rapid, non-destructive analytical tool that can be used for colored and turbid solutions. It does not require complex instruments and can distinguish the forms of different ions. It can measure samples as small as a few microliters, making it highly suitable for field analysis and automatic continuous monitoring. Compared with other analytical methods, it is particularly competitive in anion analysis. The response of electrodes to activity also has special significance, making it not only a research tool for complex chemistry and kinetics, but also used for directly observing the activity changes of certain important ions in body fluids and even cells through the miniaturization of electrodes.

The analysis objects of ion selective electrodes are very wide, and they have been successfully applied in environmental monitoring, water quality and soil analysis, clinical laboratory testing, marine exploration, industrial process control, as well as geological, metallurgical, agricultural, food and drug analysis and other fields.
