The OPTIMA7 flue gas analyzer gives abnormal readings when testing gases containing ozone
Thread Content
Help! When using the OPTIMA7 flue gas analyzer to test gases containing ozone, the NO level reads 0, and the NO2/NOX levels are equal. Has this phenomenon occurred with other flue gas analyzers as well? How to avoid it?

Furthermore, nitric oxide can be easily directly oxidized by oxygen or ozone into higher-valent dinitrogen oxides or dinitrogen tetroxide; it is normal for the NO measurement to read zero in the presence of ozone.
Ozone treatment of flue gas experiment. When the amount of ozone used is higher than that of NO, measuring NO/NO2/NOX in the exhaust gas shows a value of 0 for NO, with the concentrations of NO2 and NOX being equal
