Instrument Principle
This instrument adopts the chemiluminescence method. The basic working principle is: NO reacts with O3 to generate energized NO2, which releases energy to produce fluorescence at a specific wavelength. The intensity of this fluorescence is linearly related to the NO concentration. The photoelectric tube converts the light signal into an electrical signal to measure the NO concentration. The sample gas detection method is: the NOx in the sample gas enters the instrument and is divided into two paths. One path of sample gas enters the reaction chamber, where NO in the sample gas reacts with O3 to measure the NO concentration. The other path of sample gas enters the converter to convert NO2 in the sample gas to NO, then enters the reaction chamber to react with O3. What is measured is NO2+NO=NOx. Subtracting the NO concentration from the NOx concentration gives the NO2 concentration.
