Selecting the ideal reference electrode chemistry and form factor for a given electrochemical system can be an important decision.
Princeton Applied Research and Solartron Analytical offer a variety of options ranging from the popular Saturated Calomel Reference Electrode, or SCE, for aqueous systems to a Ag/AgNO3 reference electrode for use in organic solvents. A full list of available options is provided below.
This reference electrode is identical in physical configuration to the K0077 reference electrode except that the G0093 contains a mercury-mercurous sulfate inner element immersed in a saturated potassium sulfate solution.
The electrode is employed in situations in which the use of the saturated calomel electrode would be unsatisfactory, for example, chloride analysis, silver analysis, etc.
