Chemical hazardous materials in the pyrolysate of polyvinyl chloride have been identified using a new tandem pyrolyzer combined with a capillary GC/MS. On this study, polyvinyl chloride was pyrolyzed in a first micro furnace maintained at 600°C in helium, and then pyrolyzates were introduced again into a second micro furnace in order to obtain the further information in air circumstances. As a result, aromatic compounds, acids and aldehydes, in addition to a trace level of chlorinated aromatics such as pentachlorophenol which is one of precursor compounds of dioxine was detected. The tandem pyrolysis GC/MS system presented is very powerful analytical tool to characterize the pyrolyzate of polymers in different circumstances.
