Mass Spectrometric Studies of Reactions in Flames - Quantitative Sampling of Free Radicals from One-Atmosphere Flames

Abstract

Direct mass spectrometric sampling studies of one-atmosphere flames are described. A simple model of the sampling process is summarized which accounts for the effects and results obtained. Stable product analysis and evidence for appreciable temperature dependence of fragmentation patterns are shown. Quantitative sampling of the free-radicals H, O, OH and Cl from the burnt gas region of one-atmosphere flames is demonstrated, with direct observation of excess free radical concentrations in the reaction zones of these flames.
