Ion-selective electrode is an electrochemical sensitive element with a linear relationship between the potential and the logarithm of ion activity in a given solution, and is a kind of electrochemical sensor that uses membrane potential to determine ion activity or concentration in a solution, and its core component is the induction membrane at the tip of the electrode.
Ion-selective electrode method is a branch of potentiometric analysis, which is generally used for direct potentiometric method and can also be used for potentiometric titration.
It can determine the concentration of specific ions in solution, has a wide range of applications, and is not affected by reagent color, turbidity, etc.
Ion-selective electrodes can be analyzed in a wide range of objects, as long as the correct ion measurement method is selected,
The Ion Meter and electrode can then measure the concentration of the corresponding ion. It has been successfully used in environmental testing, water quality monitoring, soil analysis, food testing, analysis and other fields.
