Abstract
A hydrogen sulfide (H2S) detecting apparatus for measuring the concentrations of hydrogen sulfide species in a given sample is disclosed. The hydrogen sulfide detecting apparatus can comprise a plurality of reaction chambers separated from a plurality of trapping chambers by a (H2S) permeable membrane, with the reaction chambers and trapping chambers each having buffer component(s) and/or reactive agents that expose the incoming sample to a particular pH and chemical environment in order to allow for the selective liberation and trapping of hydrogen sulfide from the sample.
