Abstract
An electrochemical sensor for measurement of hydrogen sulfide is described. The electrochemical sensor comprises an electrolyte; an electrolyte container comprising a hydrogen sulfide permeable membrane; a working electrode and a reference electrode both disposed in the electrolyte; and an instrument capable of maintaining a fixed DC potential in the range of 0 mV to 1,000 mV between the working electrode and the reference electrode. Also a method of detecting hydrogen sulfide in a sample. The method comprises providing an electrochemical sensor; at least partially immersing the gas permeable membrane in the sample; and detecting hydrogen sulfide in the sample. The detection may be qualitative or quantitative.
