The Development of Simultaneous TA-MS for the Study of Complex Thermal Decomposition Reactions
As thermal decomposition is clearly a temperature dependant process thermal methods of analysis are of considerable value in both kinetic and mechanistic studies. Accordingly, differential thermal analysis (DTA) and thermogravimetry (TG) have been widely used but the results, although yielding a wealth of information, are difficult to interpret unambiguously. Hence simultaneous techniques have been develgped in which additional experimental methods are used to identify the phenomena revealed by DTA and TG (1). One such method, evolved gas analysis (EGA), has been used frequently to identify gas-loss processes and to characterise the materials evolved in thermal analysis. This paper describes the development of sophisticated EGA techniques using simultaneous DTA-MS and TG-MS to obtain qualitative and quantitative information on the gaseous products of thermal decomposition reactions.
