Portable NOx analyzer for 2 gases NO and NO2 2 in 1 gas

Portable NOx analyzer for 2 gases NO and NO2 2 in 1 gas

The challenge is not the N2O, but the NO and NO2. NO and NO2 are involved in several reactions/equilibria, that makes the quantification challenging. N2O (Nitrous Oxide), also known as "laughing gas", is quite easy to analyze via GC. One can do that on a porous polymer type phase, like the Rt Q-BOND, see fig.1.
