| Abstract | Molecular beam mass spectrometry (MBMS) and optical diagnostic techniques, two common combustion science diagnostic tools for studying the impact of material on flames, Lire evaluated as tools for estimating the gas-phase potential of polymer-flame retardant additives. The gas-phase activity of hexabromocyclododecane (HBCD), it widely used commercial flame retardant, was studied and compared via the two combustion diagnostic techniques. MBMS data for HBCD were reviewed and provided identification of gas-phase active species as well its quantitative information on the degree of effectiveness based upon reduction of OH in a premixed CH(4)/air/N(2) flame. In contrast, optical chemiluminescence detection of OH* and CH* provided it simpler technique for monitoring the gas-phase potential of flame retardants. Studies of CH* and OH* levels after addition of pyrolyzed products from polystyrene/HBCD blends into a diffusion flame system are compared with MBMS experiments of flames doped with pure HBCD. Comparison of chemiluminescence data with similar data from it small-scale heat release test, the pyrolysis combustion flow calorimeter, indicated that CH* and OH* activity relate to the heat release rate for flaming combustion.
