THOË is an autosampler that uses “passive samplers” type DGT ™ for the analysis of a range of analytes including metals and / or organic compounds dissolved in water. This device, designed by AEL / LEA and manufactured by TECHNICAP, allows the acquisition of time series data over preprogrammed time periods.
Aimed at revolutionizing the way that data is collected, THOË can be deployed for months at a time and provides a very cost-effective solution for continuous data collection.
There are many potenisal uses for THOË, including:
THOË is an autonomous automaton capable of continuously monitoring the concentrations of analytes in water up to a maximum immersion depth of 1000m, in its current version.
This configuration allows the sequential exposure of 12 DGT ™ whose individual sampling duration can be programmed to between a few hours and several weeks, depending on the environment to be monitored.
The sequences are programmed using a simple USB connection. A sensor continuously records the temperature required for concentration calculations.
The autonomy of THOË is at least 1 year.
All the components of THOË are made of inert materials: PEEK, PETP, PTFE and silicone for supports and parts in contact with DGT ™ and titanium for the axis of rotation and screws.
THOË is relatively small and lightweight, enabling it’s deployment from small vessels.
