Benchtop pH/ISE meters include two channel options in which a pH probe can be connected to one channel and the sulfide ISE to the other. The benchtop meters have the ion charge and formula weight pre-programmed for use with the sulfide ISE. The benchtop meters also have incremental methods pre-programmed including the known addition, known subtraction, analyte addition and analyte subtraction methods.
Portable pH/ISE allow the flexibility to perform an ISE measurement in spaces where there is limited bench space, then can be stored in a carrying case when not in use. The meter can accept other ISEs and has the ion charge and weight pre-programmed for the specific parameter.
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.
Solutions for sulfide measurement include the ISA for calibration and measurement. Other solutions include the Sulfide Anti-Oxidant Buffer (SAOB). The SAOB is a two component solution and is used with preparing of sulfide standards from sodium sulfide nonahydrate.
Accessories include polishing strips for the solid-state ISE and magnetic stirrers to ensure adequate mixing.
