Product Introduction

Working principle: chemiluminescence method

This instrument measures nitric oxide byNOgiveO₃The light intensity of the luminescent reaction,So as to calculate the airO₃Concentration.NOandO₃Reaction generates excited state nitrogen dioxide（NO₂^*）The excited state of nitrogen dioxide molecules releases excess energy back to a low-energy state by emitting photons, and the luminescence intensity is related toO₃The concentration is directly proportional,The light intensity signal is converted into an electrical signal by a photomultiplier tube,Determine by measuring electrical signalsO₃The concentration.

instrumentSuccessfully eliminatedSO2、NO、NO2The interference of water, toluene, xylene, particulate matter, high concentration volatile aromatic hydrocarbons, etc. on this method.
