3 Overview
The basic principle of detection equipment is nitric oxide (NO) and ozone (O3) based on a chemical reaction to produce
Excited state of nitrogen dioxide (NO2) molecules, nitrogen molecules excited state to the ground state to emit light. Light emitted
Intensity is proportional to the concentration of nitric oxide. It was detected by light emission intensity of concentration of nitric oxide detection. Its chemical
Reaction is.
NO O → 3 NO2 O2 hν
Where.
hν --- light is emitted.
The presence of nitrogen dioxide gas when the sample gas, sample gas through the instrument to the inherent converter, converted into nitrogen dioxide
Nitric oxide, then said chemiluminescent reaction with ozone. Detecting nitrogen oxides (NO NO2) Total
(NOx) and nitric oxide difference is equal to nitrogen dioxide (ie, NOx-NO = NO2) content of the gas.
General Instrument structure comprising. an ozone generator, a converter, a detector, and other electronic units.
