Model: aqms-2000 chemiluminescence analyzer.
(1) Technical principles
The basic principle of NOx analyzer is chemiluminescence. No reacts with O3 to absorb chemical energy and generate excited NO2 *.
The excited state of NO2 * is unstable, and the fluorescence is released in the form of light quantum during the process of returning to the ground state. The concentration of no can be calculated by measuring the fluorescence intensity through PMT.
The concentration of NOx is measured after all NO2 in the sample gas is converted into no by molybdenum conversion.
