Nitrogen Dioxide Gas Sensor
PSU researchers have developed a new chemical gas sensor capable of detecting nitrogen dioxide (NO2) at levels less than 100ppb (two orders of magnitude more sensitive than current chemiluminescent based NOx sensors), having a dynamic linear range of parts per million to parts per billion, and a speed of detection of 60-120 seconds. Unlike existi...

Ambient Pressure NO2 Sensor
The measurement of nitrogen dioxide (NO2) is important to both environmental monitoring and to research of flame, combustion, and surface chemistry. Current methods and devices operate at very low, sub-ambient pressures, requiring a substantial pumping system and limiting their usefulness in applications in higher pressure environments where direc...
