ECH_-5_-_ONLINE_H2S-

The S-Online for online determination of sulfides provides the opportunity to measure sulfides/H2S even below the odor threshold in wastewater. By the combination of a highly efficient gas extraction and a selective detection method, sulfide/H2S is determined in aqueous solutions.

After dosing, the sample is acidified forming H2S gas which is then degassed from the solution in the H2S analyzer. The gas is then carried into an amperometric sensor that is sensitive to detecting H2S. Therefore, interferences of the sample matrix do not affect the sensitive measurement. Even complex matrices such as industrial wastewater (e. g. containing alkaline wastewater, hydrocarbons or ammonia) can be monitored instantly as well as providing reproducible results.
