Abstract
Pyrolysis-mass spectrometry with pattern recognition has been used to analyze smoke aerosols generated in a flaming mode in a laboratory calorimeter from mixtures formulated from 10 polymeric substances were collected on glass filter. The nonvolatile materials associated with the aerosols were pyrolyzed to provide mass spectral fingerprints of the mixtrues. Factor analysis with graphical rotation generated factor spectr which were compared to reference pyrolysis spectra of aerosols from the pure polymers. An overall identification rate of 78% was achieved.
