VOC Sensors: Volatile Organic Compounds Sensor | GDS Corp

VOC sensors use a bright ultraviolet light source to knock electrons out of the VOC molecule; the electrons are measured and their flow indicates that VOC molecules are present at the sensor. Each specific type of VOC molecule has an ‘ionization potential’ (IP) value that represents the amount of energy necessary to liberate an electron; this value is measured in ‘electron volts’, or ...

VOC Sensors and Monitors - Volatile Organic Compounds

To measure a targeted VOC, a known correction factor is applied to calculate the relative value from isobutylene that is used for the sensor calibration. However, to avoid a cross interference no other VOCs should be present in the monitoring environment. For greater accuracy the sensor can be calibrated to the target VOC using a calibration gas of the target compound.
