Many of the compositional analysis applications involving thermogravimetry have focused on the determination of concentrations of one or two additives to a polymeric matrix. Paramount to the utility of such a thermogravimetric approach for filled polymers is that the matrix pyrolyzes repeatably, if not completely. Equally important is the understanding of the components constituting the high temperature residue (ash) and how they are derived. Two examples will be addressed in which controlling or understanding the chemistry of the experiment highlights the significance of the above-mentioned factors in achieving useful compositional analyses. In the first example, an ammoniated atmosphere is employed to achieve repeatable pyrolysis of silicone rubber to measure the carbon black filler content. The second example emphasizes the understanding of decomposition chemistry to distinguish two inorganic fillers retained as ash. In this example the evolution of CO2 from CaCO3 is used to identify the calcium oxide portion of the ash in a polystyrene + carbon black + silicone oil + calcium carbonate + titanium dioxide system.

The use of modern thermobalances, with high sensitivity, fast heating and cooling rates, and good atmosphere control, has allowed the routine application of compositional analysis using thermogravimetry in solving a wide range of industrially important analytical problems. Using examples drawn from experiences within their laboratory, the authors show how the technique can be extended beyond the traditional areas of proximate analysis of coals and determinations of carbon contents. Less common experimental procedures are described, including the use of reactive gases, and the study of samples in liquid and paste form.

Thermogravimetry (TG) is an analytical technique that monitors the mass of a substance as it is subjected to a controlled temperature program. TG is the modern day frontier of the much older and well-established technique of gravimetry. Although many compositional analyses may be performed by conventional gravimetry, thermogravimetry offers a more rapid method because of the smaller sample size and faster heating rates. Thus, special instrumentation requirements are imposed on the more modern, rapid, and automated thermogravimetric method. Many commercial TG systems are available. The major difference in these are in the furnace (size, design, and positioning with respect to the furnace tube and sample specimen), degree of computerization, direction of purge gas flow (horizontal or vertical) with respect to the sample specimen, and microbalance type and sensitivity. Recent years have brought computerization of data handling as well as many of the hardware components of the technique. This paper will present and discuss the role of the basic components of a thermogravimetric apparatus in performing compositional analysis. Some of the aspects of computerization of the technique will be included.
