Ion-selective electrodes
Ion-selective electrodes (ISE) are used to determine ion activities or ion concentrations directly in liquids, independent of colour and opacity. The measurement is made by immersing the ion-selective electrode and a reference electrode in the current sample solution and then measuring the cell voltage.
The reference electrodes to be used are preferably silver / silver chloride and saturated calomel electrodes. For all measuring tasks, a DC voltmeter with an input resistance less than 1010 ohm can be used. High-resolution pH measuring amplifiers with mV functionality or the ISE 40 ion meter fulfil this requirement perfectly.
The ion-selective electrodes are preferably used for determining the concentration of anions or cations in aqueous or chemical-organic/aqueous solutions. Depending on the type of ion/electrode, specific pH ranges must be set (refer to the electrode data sheets for more information).
