They are selective to H2S and remain unaffected by high concentrations of other substances like hydrogen, sulfur dioxide, and gasoline vapors, which are often present in. The Q45S model is an odor monitoring system that uses our standard Q45 electronics package in conjunction with a special Wet H2S sensor. Measurements may be either at the inlet to scrubber systems where gas concentrations can run as high as 200 PPM or at the outlet, where gas concentrations are ideally down below 0.5 PPM Answer (1 of 4): H2S is soluble in water and acts as a weak acid. it is dissociates initially into the hydrosulfide ion and then the sulfide ion. The presence of the hydronium ion, H3O+ is also present. The presence of all these intermediary ions is sufficient to conduct the flow of electrical cu..
