Thermogravimetry (TG),Measurements of changes in sample mass with temperature are made using a thermobalance. This is a combination of a suitable electronic microbalance with a furnace and associated temperature programmer. The balance should be in a suitably enclosed system so that the atmosphere can be controlled (Fig. 3.1 and section 3.4).

Less-common techniques,Under this heading, referring to Table 1.1, come emanation thermal analysis (ETA), thermomagnetometry, thermoelectrometry and thermosonimetry. These techniques are all gaining in popularity but usually require more specialized equipment which is often not commercially available as complete systems.

The literature and nomenclature of thermal analysis,A selection of references is given below to serve as an introduction to the vast literature of thermal analysis. A more comprehensive list is given in ., published by ICTA, and soon to come out in a new edition by Dr J. O. Hill.

Thermal analysis equipment,A bewildering array of equipment is available to anyone starting out in thermal analysis and selecting a suitable system is not an easy decision. It is advisable first to collect the pamphlets and specifications of most systems from the suppliers (section 16.2), and then attempt to make a preliminary selection by considering the following factors.

Introduction,ian papyri have in common? Many interesting answers could probably be suggested, but the connection wanted in this context is that they all undergo interesting and practically important changes on heating.

Thermoptometry, major technique is thermomicroscopy, i.e. direct observation of the sample. Other techniques involve measurement of total light reflected or transmitted (thermophotometry), light of specific wavelength(s) (thermospectrometry), refractive index (thermorefractometry), or emitted light (thermoluminescence).
