Preliminary study on direct measurements and diagnostics for chemical reaction dynamics of NOx by using laser wavelength modulation spectroscopy

“…During the oxidation of NO x by injection of O 3 , the chemical reaction occurs as [3] NO O 3 → NO O 2 , NO, and NO 2 are the key substances for this reaction, and the accurate determination of these substances during the reaction is necessary to understand the reaction process of NO x oxidation by O 3 . For the diagnosis of these substances, conventional extraction sampling probes combined with gas chromatography or mass spectrometry are usually used [4] , however, the relatively long response time, invasiveness, and potential secondary chemical reactions during the sampling process limit their application for chemical reaction process measurements.…”
