A new analytical methodology for water emerges with the development of DGT® technology coupled with the THOË® automatic sampler developed by AEL/LEA and built by TECHNICAP.
For example, for many years environmental monitoring of the marine environment has been conducted on the basis of spot sampling of water. This type of strategy generates significant logistical costs and makes the acceptance of high frequency sampling difficult.
The performances of this new methodology have been compared to the spot sampling of waters for dissolved metal pollutants. In the example of monitoring the port of Nouméa (New Caledonia), the results underline the remarkable similarity of the concentrations between the three different methodologies, but with the advantage for THOË to obtain time series without the typical logistical constraints.
THOË® is designed to be submerged up to a depth of 1000 m.. It can be fixed on a mooring line, placed on the bottom using feet attachments (optional legs) or deployed on the surface of the water (optional float).
