Submersible H2S/Sulphide Probe

Submersible H2S/Sulphide Probe
In-situ measurements and profiling in shallow water

Accurate - Reliable - Small Dimensions - Easy Handling

The determination of total dissolved sulphide (sum of dissolved H2S, HS- and S2-) is one of the most important parameters for the analysis of natural waters and waste water in industry.

It is necessary to observe the total sulphide concentration, dissolved in water, to avoid any danger because of the evaporation of the very toxic H2S. H2S is able to block oxygen transporting enzymes leading to the death because of inner suffocation. On the other hand, the total dissolved sulphide concentration is an interesting parameter for scientists of several scientific departments. They use this parameter for the assessment of natural lakes, but also for instance to understand volcanic activities.

But due to a lot of the hydrogen sulphide’s inconvenient chemical properties, like high chemical reactivity, very fast oxidation in the presence of oxygen and the fast concentration exchange between the liquid sample and the gaseous phase above (mostly air), the determination is difficult. Even though the sampling and the determination have been done very carefully, the results are uncertain and mostly disappointing.

All these disadvantages could be avoided, if the new Submersible H2S/Sulphide Probe is used for accurate and reliable the in-situ determination in depths of up to 100 m.
