Journal Article
Horn, J. J., Wadhawan, J., & Mccreedy, T. (2010). Amperometric measurement of gaseous hydrogen sulfide via a Clark-type approach. Analytical Methods, 2(9), 1346-1354. doi:10.1039/c0ay00338g

The direct oxidation of hydrogen sulfide in the range 2.0-20 parts per million by volume (ppmv) using a Clark-type amperometric gas sensing methodology is investigated via amperometric transients at 298 K. The diluent gas employed is air (20.9% O-2 i... Read More
