An ion meter is a device used in laboratories and industries to measure the concentration of ions in a solution, by using ion electrodes (ISE) thanks to its electrochemical activity. An ion selective electrode (ISE) is a kind of sensor that allows ion testing in various types of samples. The process that these electrodes work with is ion exchange, which measures the potential difference that is produced by the contact of the electrode with the ion being determined.
These innovative equipment currently have many utilities, but it is used more frequently to measure and control water purity. Because pure water is required for many laboratory and clinical procedures. Moreover, that drinking water for consumption, should be as optimal as possible to avoid diseases and health conditions of people.
What is an ion?
An ion is an atom or group of electrically charged atoms. This molecule may have a positive or negative charge. A cation is an ion with a positive charge and an anion is one with a negative charge (atom or molecule).
Ions are formed when a neutral (electrically neutral) atom loses or gains electrons. Anions have more electrons than protons and cations have a higher proton number.
How does an ion meter work?
Measurement of ion concentration or specific ion measurements via an ion meter can be performed on a wide variety of samples such as: water, food, beverages, pharmaceuticals and also samples of biological origin. The operation of an ion meter occurs by means of selective ion electrodes (SIIs) and measuring devices that have a sensitive membrane capable of measuring ion activity. These measure the concentration of ion determined in a solution using a sensor electrode and a reference electrode.
They work, as we mentioned earlier through ion exchange, where you measure the potential difference that is generated when the electrode comes in contact with the ion being studied. The specific ion activity is transformed into electrical potential at the moment it comes into contact with the active membrane of the selective ion electrode. Thus, the measurement process in an ion meter is carried out by the use of two electrodes: the sensor and the reference sensor. The sensor electrode takes care of the selectivity of a specific ion. And the reference electrode is used to calculate the potential difference.
