The primary scope of TG-GC-MS coupling is to detect, separate and analyze organic components. It is also possible to use the coupled GC-MS for detailed gas analysis to further improve the temperature-programmed pyrolysis of organic materials, biomass, renewable solid fuels, carbonaceous materials, and polymers in the TG/STA. The volatile products emitted during combustion processes can be determined with high sensitivity and resolution at various oxygen content levels.
