We report here experimental results for a nitrogen dioxide sensor based on optical transmission through porous silica fiber. The NO2 optrode is activated by using a proprietary chemical pretreatment process on the porous silica. Light is coupled to and from the porous silica optrode via 600 micrometers diameter optical fibers. The peak response of the sensor is at approximately 420 nm and therefore can be monitored using a blue LED. The sensor demonstrated a reversible, full-range response from 0 to 10,000 ppm NO2 in a balance of nitrogen. The sensor also demonstrated a sensitivity of 10 ppm. The range and sensitivity of this sensor make it suitable for monitoring nitrogen dioxide emission from combustion stacks.
