The Action of Hydrogen Sulfide on Polarographic Oxygen Sensors
It is often necessary to measure oxygen concentrations in water containing dissolved hydrogen sulfide (Chap. III.l). Conventional polarographic oxygen sensors (POS) fail within a very short time under such conditions, for a variety of reasons to be described in this article. The principle of the modified sensor made by Orbisphere which may be exposed to high concentrations of H2 S is also described.
