NOx species, not by-products of the purification of air, with high temperature combustion devices for biological studies

Abstract

The production of oxides of nitrogen can occur with high temperature combustion devices operated in the presence of molecular oxygen and nitrogen. However, such was not the case under the conditions used for the purification of air for biological studies. After analysis of air for total NO and NO₂, we found that the passage of air through catalysts at 650 °C did not increase the amount of NO_x in the air stream.
