Abstract

This disclosure relates to sulfur sensors that utilize sensing materials that can be used to detect ultra low concentrations of sulfur in liquids, such as below even 15 ppm. The sulfur sensors comprise a sensing electrode having a material that contributes an electrical element to the analysis and a material that contributes an ionic element to the analysis.
