热分析结合逸出气体分析已经使用了一段时间。热重分析（TG）结合傅里叶变换红外（FTIR）光谱（TG/FTIR）、热重分析（TG）结合质谱（TG/MS）和热重分析（TG）结合GC/MS提供了在热过程中形成的化合物的结构鉴定。这些逸出气体分析（EGA）技术允许通过确定分解产物来评估降解反应的化学途径。本文将介绍TG/FTIR、TG/MS和热解/GC-MS系统及其在几种材料研究中的应用，包括有机改性粘土、聚合物和煤混合物的降解机理分析。
Thermal analysis combined with evolved gas analysis has been used for some time. Thermogravimetry (TG) coupled with Fourier transform infrared (FTIR) spectroscopy(TG/FTIR), Thermogravimetry (TG) coupled with mass spectrometry (TG/MS), and Thermogravimetry (TG) coupled with GC/MS offers structural identification of compounds evolving during thermal processes. These evolved gas analysis (EGA) techniques allow to evaluate the chemical pathway of the degradation reaction by determining the decomposition products. In this paper the TG/FTIR, TG/MS, and Pyrolysis/GC-MS systems will be described and their applications in the study of several materials will be discussed, including the analysis of the degradation mechanisms of organically modified clays, polymers, and coal blends.
