Volatile organic compound Wikipedia

Volatile organic compounds (VOC) are organic chemicals that have a high vapour pressure at room vapor pressure correlates with a low boiling point, which relates to the number of the sample''s molecules in the surrounding air, a trait known as volatility.. VOCs are responsible for the odor of scents and perfumes as well as pollutants.

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

For VOC monitoring, selective identification of hazardous VOCs down to concentrations of 1 ppb could be demonstrated even in a background of other VOCs of several ppm and against changing humidity using a commercial ceramic MOX sensor at least under lab conditions ; similarly, quantification of VOCs at low ppb levels was demonstrated with this approach both for MOS and SiCFET [15,37] sensors.

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 ...

Environmental Sensors | Sensirion

Sensirion’s powerful VOC Algorithm analyzes VOC events detected by the SGP40 sensor and maps them to a VOC Index. This VOC Index provides a practical quantification of VOC events relative to each individual sensor’s typical indoor environment. In this way, it behaves similarly to the human nose, which is highly susceptible to changes in odor, but it also detects VOC events that are not ...

VOC Sensors and Monitors Volatile Organic Compounds

Aeroqual VOC Sensors. Aeroqual offers two types of VOC measurement sensors; Photoionization Detector (PID), and Gas Sensitive Semiconductor (GSS). Both sensor types are nonselective which means they can be used for measuring a wide variety of VOCs. To achieve this they have been calibrated against isobutylene that allows them to respond to a wide range of VOCs at varying degrees of ...
