VOC Sensor - Alphasense - PDF Catalogs | Technical ...

VOC Sensor p-type Metal Oxide This sensor is a broadband total VOC detector. When the cost of a PID is not justifiable, this sensor will detect VOCs with 10-50 ppb limit of detection, depending on the VOC. Unlike common n-type sensors, this metal oxide sensor has a large dynamic range, repeatable response, low humidity response and resistance ...

Operating principle ‐MOS-type gas sensor

Here [e] S is the surface electron concentration of particles and L D is the Debye length. R and R 0 is the sensor resistances at the steady state and flat band state, respectively. For other symbols, see the caption of When sensor materials are selected, N d, a, L D and R 0 are fixed, while p is dependent on the actual gaseous conditions. As described above, MOS type gas sensors change ...

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.
