Cyanide electrodes are potentiometric devices used for the rapid determination of free Cyanide ions in effluent, for electroplating bath analysis and as a detector for titration of cyanide with silver nitrate. The electrode functions as a sensor or ionic conductor. The silver halide pellet is practically insoluble in the test solutions being measured and produces a potential change due to changes in the sample’s ion activity. When the ionic strength of the sample is fixed by the addition of ISA, the voltage is proportional to the concentration of Cyanide ions in solution and the electrode follows the Nernst equation.
The cyanide ISE is available as a combination version with both indicating half cell and reference half cell or available as an indicating half cell that will be used with a separate reference half cell.
