Shallow Water Micro-sensor for Dissolved Hydrogen
For very fast depth profiling with probe systems
The amperometric micro-sensor for shallow water has been developed for the fast insitu depth profiling of dissolved hydrogen with probe systems in natural waters and oceans. Because of the partial
pressure of the gaseous H2 , the analyte is separated by permea-tion through the membrane. Inside the sensor the hydrogen reacts electrochemically at the working electrode. This causes a current
corresponding to the partial pressure of the dissolved hydrogen.
