Highly Sensitive and Selective VOC Sensor Systems Based on ...

One candidate sensor principle for direct monitoring of even subppb level VOC concentrations are metal oxide semiconductor (MOS) gas sensors [13,14], but gassensitive field effect transistors (GasFETs), , based on silicon carbide (SiCFET), have also proven their suitability for this task . For simplification, we will concentrate on MOS sensors in the following discussion, but many aspects also apply to SiCFET sensors, so the approach is presented for semiconductor gas sensors…

VOC Sensors Belimo

1 VOC Sensors What are VOCs VOC is an abbreviation for Volatile Organic Compounds and a collective term for gaseous carbonaceous substances. Depending on how high the concentration of these substances in the ambient air is, we can perceive them by smelling them with our nose. On average, a person inhales about 15 kg of air per day, 80% of it indoors. Outside air quality is routinely ...
