The basic operation, its critical test procedures, and its application are explained of the thermogravimetric Analyzer (TGA), one of a number of thermal analysis techniques considered as geosynthetic 'fingerprinting' tools. The technique uses an instrument containing a thermobalance that permits the continuous weighing of a sample as a function of temperature. Any reactions that induce a weight change within the sample can be detected. The instrumentation, and testing techniques are described, and it is noted that TGA is a useful tool to measure the various proportions of different components' compositions in a specific geosynthetic material, as well as their corresponding decompositon temperatures. For multicomponent decomposition products such as PVC (polyvinyl chloride) and chlorosulphonated polyethylene geomembranes, the technique is very valuable.
