Abstract
This disclosure relates to sulfur sensors that utilize sensing materials that can be used to detect a wide range of concentrations including 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 electronic output to the analysis and a material that contributes an ionic output to the analysis.
