Electrodes & Probes

Sulfide ion determinations are made in ground waters, soils, and paper liquors. The silver/silver-sulfide 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 sulfide ions in solution and the electrode follows the Nernst equation.

The sulfide ISE is available as either a single half-cell or combination design that is complete with a reference cell. The ISE is a convenient way to measure sulfide.
