Thermal analysis (TG/DTA) combined with mass spectrometry is a powerful tool for studying thermal decomposition mechanisms of materials. The sensitivity of the thermal analysis of TG-MS has increased. Computers have had a marked impart on the operation of thermal analysis widely. The history of the development of TG-MS, the principle of measurements, the appratus and results of the measurements, and the discussions are widely reviewed. And the future application of TG-MS was also discussed. The kinetic parameters of reaction rate of the TG-MS meausurements were analyzed using by Lord-Kittelberger method. Thermal decomposition mechanisms of several materials were also discussed. New techniques of TG-APCIMS/MS was discussed for new introduction of the evolved gases and the precise identification of ions. Moreover the simultaneous thermogravimetric modulated beam mass spectrometry (STMBMS) and time-of-flight (TOF) velocity-spectra were also discussed for the spot of production of evolved gases.
