Working Principle

1The instrument adopts the principle of chemiluminescence detection. The sample undergoes high-temperature oxidation reaction, and the nitrogen compounds in it are quantitatively converted into NO2. The sample gas is dehydrated by a membrane dryer and enters the reaction chamber. The metastable NO reacts with O3 from the ozone generator in the reaction chamber and is converted into excited NO2. When the excited state of NO2 transitions to the ground state, photons are emitted, and the light signal is detected and received by a photomultiplier tube at a specific wavelength. By amplifying microcurrents and processing computer data, it can be converted into an electrical signal proportional to the intensity of light. The intensity of chemiluminescence is proportional to NO, and the amount of NO generated is proportional to the total nitrogen content in the sample. Therefore, the total nitrogen content in the sample can be determined by measuring the intensity of chemiluminescence.
