Boqu Pxg-2085PRO Replaceable Membrane and Electrolyte Isa Standard Hardwater Online Ca Calcium Ion Sensor Probe Electrode

An Ion Selective Electrode measures the potential of a specific ion in solution. This potential is measured against a stable reference electrode of constant potential. The potential difference between the two electrodes will depend upon the activity of the specific ion in the solution. This activity is related to the concentration of that specific ion.

Standard solutions of known concentrations must be accurately prepared. These solutions are then measured with the pH/mV meter. The mV reading of each solution is noted and a graph of concentration vs. mV reading must be plotted. The unknown solution can now be measured. The mV value of the unknown solution is then located on the graph and the corresponding solution concentration is determined. Dedicated ion meters can construct a calibration curve automatically.

ISEs are not ion-specific. All are sensitive to some other ions to some extent. For many applications, these interferences are insignificant (unless there is a high ratio of interfering ion to primary ion) and can often be ignored. In some extreme cases, however, the electrode is far more sensitive to the interfering ion than to the primary ion and can only be used if the interfering ion is only present in trace quantities or even completely absent. The ability of an ion-selective electrode to d

The instrument is suitable for F-, Cl-, Ca2+, NO3-, NH4+, NH3, CO2, Cu2+, S2-, and Hardness.
