Technology offer : Trace element sensor

Technology's description

Trace metals are often difficult to quantify in the natural environment. To make these measurements, "passive" sensors are used. They are deployed on-site for several days to obtain a sufficient concentration of pollutants. These devices have some limitations: uncertain reliability, low sample surface, biofouling problems, drift, etc.

The IRD and the Geosciences Environment Toulouse laboratory (GET) have developed a sensor that allows to overcome all these drawbacks : Tracesense.

Tracesense is concentrating pollutant through a porous blade which is having its surface artificially "increased" thanks to an ingenious system of vibration. The sampling period is 200 times faster than a "passive" sensor and is reduced to a few seconds. Robust and easy to use, Tracesense is for any type of user.

Furthermore Tracesense contains a light sensor, an altimeter and a temperature sensor that characterize the sampling environment. These data can be extracted via a mobile application to a database.

Developed for the measurement of mercury, the technology is adaptable to any trace element. The prototype was tested in Bolivia on Titicaca's lake.
