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.

20201001· The detection limit was found to be ppm for THF and ppm for benzene. To make the sensor user friendly, we have designed a set up where VOCs can be detected using a smartphone if the VOC concentration is above 50 ppm. This method can be utilized for the detection of VOCs in realtime and portable basis.
