This paper refers to an analytical technique by a tandem DTA-GC-MS combined system and describes our experiments to analyze polyacrylonitrile(PAN)resin and Nylon6in different atmospheres of air and inert gases. The DTA-GC-MS tecnique not only provides informations on the behaviors of samples under heating but also qualitatively determines the gases evolved during the process of heating. The GC-MS identified HCN evolved from the PAN resin samples and HCN and NH, evolved from a Nylon6sample using a Chromosorb103column, and acetonitrile, vinyl-acetonitrile, methylbutene, cyclohexane, toluene, pro panenitrile and2-methyl-propanenitrile evolved from the PAN resin sample, using a PEG-20M column.
