Selective SAW-Based Carbon Monoxide Differential Sensor Functionalized with Cobalt Corroles: Influence of Interfering Gases

摘要

During the last two decades, the potential impact of indoor air quality on human health has stimulated an interest in hazardous compounds survey such as carbon monoxide (CO). The French Institute for Health Surveillance (InVS) reports that accidental domestic poisoning by the CO affects about 1000 households in France each year, and is responsible for about 100 deaths. The detection of this compounds has consequently become a need. To address it, we here report results on the capability of functionalized Surface Acoustic Wave (SAW) devices for the selective detection of CO. Here we insist on the necessity to detect CO in presence of interferent such as O_2 that is obviously present in the air and CO_2 present in significant quantity in urban area.
