NO2 analyzers are much more valuable if they can also measure NO since the two (NO+NO2=NOx) are often found together. NO can be quantitatively converted to NO2 by reaction with ozone and subsequent thermal decomposition of the N2O5 that may form from further oxidation. The conversion of NO, along with decomposition of N2O5 and removal of the remaining unreacted ozone with a heated chamber, allows for quantitative determination of NOx using a NO2 analyzer and the determination of decomposed acyl peroxynitrates. Ambient tests are performed to demonstrate these methods.
