Preoxidation for Colorimetric Sensor Array Detection of VOCs

· While these colorimetric sensor arrays work exceedingly well for reactive volatiles, they have not had especially high sensitivity to less reactive vapors. 14f For example, common VOC indoor air pollutants (, aromatic hydrocarbons, chlorocarbons, other organic solvents) are generally not especially reactive and are not detected at low concentrations by our colorimetric sensor array. We ...

Highly Sensitive and Selective VOC Sensor Systems Based on ...

Further sources of error can be due to either VOC sources inside the system, , from lubricants in valves or mass flow controllers, or due to adsorption of VOCs on inner surfaces preventing the target gas from reaching the sensor. The latter is especially problematic von SVOC which will then slowly diffuse out of the system, which can lead to large carryover or “memory” effects. These effects can only by …

Beyond CO : Sensing VOCs in Indoor Air Protects Health ...

While sensors that can reliably measure temperature, humidity, and detect CO 2 (IR absorption) are commonplace, metal oxide gas sensors that detect VOCs are now also available. VOC sensors are produced by placing a semiconducting, nanocrystalline metal oxide on a substrate heated to between 300° to 400°C and measuring the conductivity. By adding dopants of noble
