NETHELIX

Portable multi-gases analyzer based on QCL source

NETHELIX project is a visionary undertaking aimed at revolutionizing the mining sector thanks to its real-life settings a toolbox of new technologies for automating and streamlining the extraction process. These technologies will make use of mining and waste deposit processing methods, maximizing efficiency, reducing waste production and increasing environmental and human health safety.

In the frame of NETHELIX, Alpes Lasers is partnering with Ulm University to develop novel smart portable sensors able to simultaneously measure and control the concentration of gases deemed harmful to operators in underground and open-pit mines.

The sensor will leverage the benefits of Quantum Cascade Lasers (QCL), a technology pioneered by Alpes Lasers 25 years ago. QCLs are mid-infrared laser sources, whose emission wavelength can be very precisely tuned to the absorption peaks of targeted gases, allowing detection sensitivity down to the part per million (ppm) or part per billion (ppb). The sensor will be able to detect dangerous gases, identify their nature, measure their concentrations, as well as to trigger alert and emergency systems if needed. All of this in a compact and portable device.
