Principle
Chemiluminescence relies on the reaction of NO with ozone. The chemical oxidation of NO by ozone yields NO2 in an excited state. Relaxation from this excited state produces distinctive light emission (chemiluminescence) that is directly proportional to NO concentration.
The intensity of light emitted is directly proportional to the concentration of NO.
