Phosphine (PH3) - a possible biosignature on rocky planets - was detected in significant quantities in Venus’ atmosphere. With absorption spectra in the mid-IR, Alpes Lasers QCLs are uniquely suited for measuring phosphine even at extremely low concentrations. See how our QCLs have recently been used to measure PH3 concentrations.

Monitoring Water Quality using QCLs

WaterSpy is a consortium of 10 partners, including Alpes Lasers, funded by Horizon 2020, the EU Framework Programme for Research and Innovation for 2014-2020 in order to develop water quality analysis photonics technology suitable for inline, field measurements.

At the completion of the project in 2020, the WaterSpy module was extensively tested in the labs of partners in Austria, Germany and Italy, followed by a real-world demonstration at a water treatment plant near Genoa in Italy. While a full sample analysis of 100 ml of water may take up to 3 days using current laboratory analysis systems, the WaterSpy portable device takes no more than 7 hours to conduct an equivalent analysis, and is therefore less costly. It also complies with the latest EU drinking water regulations.

This system only requires two standard Quantum Cascade Lasers to perform the analysis. Do not hesitate to contact us for more information!
