Towards a Portable Multi-Gas Sensor for Environmental Gases with Miniaturized Photoacoustic Cells and Mid-Infrared Quantum Cascade Lasers

Current issues on air pollution monitoring or greenhouse gases emissions rely on the sparse use of expensive gas sensors. We target to develop a portable miniaturized sensor with the capacity of being gas-specific, lightweight and autonomous. We present here results obtained with our newly packaged Photoacoustique Module. We also present the development of its dedicated electronic companion system.
