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 SiC-FET [15,37] sensors.

Applications of PID Sensors in VOC monitor systems in ...

22-01-2019 · Conventional VOC gas detectors often use sensors based on catalytic combustion, so they respond slowly to C5 and gas over it, and may easily be poisoned. PID detectors solve such problems well. With fast response and no poison, they can be used as VOC gas detectors down to PPB level.PID is a kind of photoionized detector with high sensitivity and a wide range of application.

Influence of VOC structures on sensing property of SmFeO3 ...

31-10-2014 · To confirm the sensor response law, the characteristics, α (= K VOC 1 + K O 2 C O 2 1/ n) and m, were estimated for the experimental results with the standard deviation, R 2 and summarized in Table 1.The proposed sensor response law satisfies the observed sensor response of the VOC. It seems that the characteristic, K O 2 C O 2 1/ n, is hardly influenced by the VOC gas concentration.
