Ion meter

Today's ion meters are based on the ion-selective electrode technique. These are measuring instruments that have a sensitive membrane capable of measuring ionic activities. That is, they measure the concentration of a given ion in a solution using both a sensing electrode and a reference electrode.

The methodology used by ion meters with selective ion electrodes is ion exchange, which measures the potential difference produced by the contact of the electrode with the ion being analyzed.

To carry out the ion measurement, the ion selective electrodes must come into contact with a certain ion present in the solution. Since the main concern of this measurement is the concentration, and not the activity of the ions in the solution, many times salts are used that increase the ionic strength to facilitate the relationship between the potential of the electrode and the concentration. The activity of the specific ion is converted to electric potential when it comes into contact with the active membrane of the ion-selective electrode. Once this conversion is carried out, the electrical potential can be measured with a voltmeter or with a pH meter.

Ion meter in operation

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.
