Zur Quantitativen Bestimmung von Stickoxiden im Zigarettenrauch mit Hilfe der Chemilumineszenzmethode

Abstract

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.
