Paper Abstract

The detection and quantification of trace gases is of great interest in a wide range of applications such as environmental monitoring, industrial process control and medical diagnostics. In combination with quantum cascade lasers, photoacoustic spectroscopy offers the advantage of high sensitivity (parts per billion detection limits), compact set-up, fast time-response and simple optical alignment. We will report here on the design and fabrication of optoacoustic sensors based on two different cell configurations to detect nitric oxide and formaldehyde.
