Model 801
Chemiluminescence NO-NO₂-NO_x Analyzer

Principle of Operation

Chemiluminescence corresponds to an oxidation of NO molecules by O₃ molecules: NO + O₃= NO₂* + O₂. The return to a fundamental electronic state of the excited NO₂* molecules are made by luminous radiation in a 600-1200 nanometers spectrum: NO₂*NO₂ + hv, Where:h- planck constant, v- frequency of photons emitted. The radiation measurement is made by a photo-multiplier. The electrical signal it delivers is amplified and digitized for treatment by the microprocessor. Nitrogen dioxide (NO₂) must first be transformed into NO before it can be measured using the luminescent reaction. NO₂ is converted to NO by a molybdenum converter heated to about 200 ℃
