Although the sound waves cannot be perceived directly by the human ear, the acoustic signals can be measured using microphones and the molecular concentration can be determined.
This amazing principle is used in the TRACE-GAS PAS sensors to determine the concentration of gases. The photoacoustic technology platform offers many design options to realize low-cost and highly sensitive quantification of trace gases. Depending on the gas molecule, a wide variety of light sources can be used: from the ultraviolet to the mid-infrared range, LEDs, UV lasers, ICLs or even QCLs can provide the ideal solution for a measurement task.
