Currently there are no standards or limits for indoor air levels of nitrogen oxides; for reference ... The outdoor annual average limit for NO 2 is set at .053 ppm. Note that most pods do not contain ...

Dinitrogen gas (N 2) is the ultimate end product of denitrification, but other intermediate gaseous forms of nitrogen exist (Figure 7). Some of these gases, such as nitrous oxide (N 2 O), are ...

Because nitrogen is not an oxidizing gas, adding it to the SMT convection reflow oven reduces oxidation on the welding ...

While that may seem likely, we also emit compounds like nitrogen oxides (from engines and power plants) that increase OH production. Which of the two processes dominates and whether OH levels are ...
