Continuous Monitoring of Dissolved CO2 and H2S: Technical ...

Commercial sensors to monitor dissolved CO2 and H2S in seawater are so far unavailable. Therefore a sensor device based on commercially available sensors for gas monitoring was designed, constructed, and tested. The sensor array was tested in the submarine hydrothermal system of Panarea, Aeolian Islands, Italy. The first application provided important insight into variations of CO2 and H2S ...

HYDROGEN SULFIDE MEASUREMENT AND DETECTION

· S sensor technologies include metal oxide sensors, sometimes called solid ceramicmetallic (cermet) film devices, and electrochemical cells. Each of these devices depends on the migration of H 2 S from its source to the sensor and can be incorporated into a fixedpoint detection system or carried by the individual.

H2S Microsensor Unisense

The sensor signal is generated by reoxidation of ferrocyanide at the anode in the tip of the sensor (Jeroschewski et al. 1996). The internal guard electrode facilitates a constant ratio of ferri to ferrocyanide in the electrolyte, thus minimizing the zerocurrent. The ferri/ferrocyanide complex is light sensitive and the sensors are painted black to minimize light interference.

Shallow Water Hydrogen Sulphide Microsensor

insitu determination of dissolved H2S/Sulphide in natural waters. Because of the partial pressure of the gaseous H2S, the analyte is separated by permeation through the membrane. Inside the sensor the hydrogen sulphide reacts with a redox mediator. The reoxidation at the working electrode causes a current corresponding to the concentration of the dissolved molecular H2S amount. The sensor has ...
