Abstract
We will report on the design and realization of optoacoustic sensors based on commercial quantum cascade lasers for environmental analysis applications. Different configurations will be described: i) sensors based on resonant photoacoustic cells, a "standard" H cell and an innovative T-cell; ii) sensor based on quartz enhanced photoacoustic spectroscopy. We will analyze the results obtained in the detection of nitric oxide.
