Abstract
The exposure to volatile organic compounds (VOCs) constitutes a serious environmental health concern. Currently, different typologies of sensors are able to track the VOCs presence in workplaces, but they are limited in terms of chemical selectivity and sensitivity. Here, we apply Infrared (IR) spectroscopy combined to a multipass cell in order to extend the sensitivity of this technique down to the part per million (ppm) level. We calibrate the system for four compounds of interest and finally test the recognition performances on mixture of VOCs.
