[Quantitative determination of nitrogen oxide in cigarette smoke by means of chemiluminescence (author's transl)]. 1977

H J Klimisch, and E Kirchheim

A measuring method with a chemiluminescence-analyzer is developed for determining the content of nitrogen oxide in cigarette smoke. This method is suitable for puff/puff analysis. It could be demonstrated that a determination of fresh smoke is necessary as nitrogen oxides react very quickly with other constituents of the vapor phase. Measured values have to be corrected for a quench factor in analogy to the CO2 concentration, as carbon dioxide shows an influence on the measuring sensitivity of the chemiluminescence-analyzer.

D009569	Nitric Oxide	A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.
