Detecting VOCs with PID - how it works - Crowcon

Having recently shared our video on pellistors and how they work, we thought it would make sense to also post our video about PID (photo-ionisation detection). This is the technology of choice for monitoring exposure to toxic levels of another group of important gases – volatile organic compounds (VOCs). The sensor …

Highly sensitive VOC detectors using insect olfactory ...

This paper reports a volatile organic compound (VOC) sensor based on olfactory receptors that were reconstituted into a lipid bilayer and used in a specifically designed gas flow system for rapid parts per billion (ppb)–level detection. This VOC sensor achieves both rapid detection and high detection probability because of its gas flow system and array design.
