  • Publication number: 20120073988
    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.

  • Publication number: 20080164156
    Abstract: A method of detecting and measuring levels of a sulfur-containing amino acid in a sample is provided. The method includes combining an enzyme with an aqueous solution possibly comprising a sulfur-containing amino acid. When a sulfur-containing amino acid is present in the solution, it reacts with the enzyme and produces hydrogen sulfide or ammonia. An electrochemical sensor is employed to detect the presence of hydrogen sulfide or ammonia in the solution, and thereby detect the presence of sulfur-containing amino acid. The concentration of sulfur-containing amino acid present in the sample can be quantitatively measured or calculated using this method.
