Project description:
The objective of this project is to develop a compact, submersible FTIR (Fourier-Transform Infrared spectroscopy) sensor platform for the online detection of per- and polyfluoroalkyl substances (PFAS) in aqueous environments.
Unlike current laboratory-based methods such as LC-MS, the proposed system will enable continuous, real-time monitoring directly in rivers, lakes, or water treatment systems without the need for manual sampling or transportation. The primary innovation of the project lies in adapting infrared spectroscopy for underwater operation and integrating automated sample pre-concentration to overcome the sensitivity limitations of FTIR in water analysis.
The platform will combine a short-path optical interface with built-in electronics and pump-driven water intake.Features integrated real-time spectral analysis.
Development Stage: Within 12 months, the project will advance from TRL 2–3 to TRL 4, focusing on the proof-of-concept for the core technology.
The team, which possesses extensive experience in autonomous underwater sensor development, will manufacture the optical, electronic, and mechanical subsystems in-house.
Industry partners from the water supply sector will provide user feedback and define application scenarios. The project will result in a unique sensor platform for detecting PFAS—often referred to as "forever chemicals"—in water. This will facilitate early warning systems, ensure regulatory compliance, and enhance environmental protection across Europe.
