Archivio Istituzionale della RicercaA new simple and low-cost fiber optic sensor for cumulative detection of H2S and other sulphide compounds is described. The transducer is based on a plastic optical fiber and exploits a non-reversible chemical reaction, whose products interact with the evanescent field tails thus increasing the propagation losses with the exposure time. The sensor has a sensitivity of the order of few ppb.

Abstract
A new simple and low-cost fiber optic sensor for cumulative detection of H2S and other sulphide compounds is described. The transducer is based on a plastic optical fiber and exploits a non-reversible chemical reaction, whose products interact with the evanescent field tails thus increasing the propagation losses with the exposure time. The sensor has a sensitivity of the order of few ppb.
