title: Electrochemical determination of hydrogen sulphide in air.
abstract: A new method for the quantitative analysis of sub-ppm and high ppm levels of hydrogen sulphide is reported. The technique is based on the electrochemieal oxidation of hydrogen sulphide at a potentiostatically-controlled. Teflon-bonded diffusion electrode. Two instruments (one portable and one a fixed-location instrument) were constructed and their operating characteristics evaluated. They were sensitive and selective, responded rapidly to the gas. and gave a linear relationship between steady-state signal and gas concentration. Excellent zero and signal stability indicate that the electrochemical sensor is not poisoned by the H(2)S.
