Abstract

Thermal analysis methods have ben used for many years for material characterization. In recent years, thermal methods have been coupled to other methods of chemical analysis to obtain more complete material characterization. This study looks at thermal decomposition of polymer samples as well as coal samples in atmospheres of nitrogen and air. The thermal analysis instrument used was coupled to a Gas Chromatograph (GC) and a Fourier Transform Infrared Spectrometer (FTIR) so that the gaseous products evolved during thermal decomposition could be analyzed. The results obtained show that the coupled techniques of TG -GC and TG-FTIR can show pyrolysis and combustion of different materials.
