How Does a TVOC Sensor Actually Work?

The sensor will be sensitive to a wide variety of VOCs, rather than to one specific individual VOC. How does the change in resistance become a TVOC reading in ppb? Although similar, different VOCs will have slightly different reactions the same increase in formaldehyde and in ethanol might not lead to the exact same change in resistance on ...
