Applications of simultaneous thermogravimetry-mass spectrometry in polymer analysis

Phases and thermal decomposition characteristics of hydro-sodalites Na6+x,[AlSiO4]6,(OH)x·nH2O

INTRODUCTION Combining thermal analysis (TA) with gas-analykal techniques significantly enhances the possibilities for correctly interpreting the mechanism of thermally induced reactions, which involve the formation of gaseous species. Several techniques can be used for evolved gas analysis (EGA), ranging from simple, non-specific detection to the more elaborate multidimensional/multifunctional methods, such as gas chromatography (GC), infrared spectroscopy (IR) or mass spectrometry (MS), for gas detection and analysis [1]. While the GC methods were used as early as the 1960s [2], EGA by FTIR was described much later and was used for the analysis of pyrolytic and combustion products. Presently, there are several commercial FTIR systems available that can be coupled to a thermogravimetric analyzer (TGA), and a broad range of applications have been investigated by this important hyphenated technique [3].
