Abstract
We present the principles and development of a transportable trace gas sensor based on a broadband mid-infrared spectrometer utilizing a supercontinuum laser source. The sensor is able to simultane-ously detect multiple gas species, including various hydrocarbons, aldehydes and alcohols in real-time with sub-ppmv sensitivities. We demonstrate the application of our sensor in real-time measurement of the volatile compounds produced due to the respiration of the fruits in the storage facilities, providing a tool for monitoring the status of the stored fruits and minimizing the fruits wastage.
