Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Validating the specifications, value and safety of your raw materials, products and assets.
Formally confirming that your products and services meet all trusted external and internal standards. Thermogravimetric TGA analysis provides determination of endotherms, exotherms, weight loss on heating, w1131, and more. Materials analyzed by TGA include polymers, plastics, composites, laminates, adhesives, food, coatings, pharmaceuticals, organic materials, rubber, petroleum, chemicals, explosives and biological samples.
Thermogravimetric Analysis (TGA) ASTM E, ISO
Thermogravimetric analysis uses heat to force reactions and physical changes in materials. TGA provides quantitative measurement of mass change in materials associated with transition and thermal degradation.
TGA records change in mass from dehydration, decomposition, and oxidation of a sample with time and temperature.
Characteristic thermogravimetric curves are given for specific materials and chemical compounds due to unique sequence from physicochemical reactions occuring over specific temperature ranges and heating rates. These unique characteristics are related to the molecular structure of the sample.
Thermogravimetric Analysis measures the percent weight loss of a test sample while the sample is heated at a uniform rate in an appropriate environment.
ASTM E – 03 Standard Test Method for Compositional Analysis by Thermogravimetry
The loss in weight over specific temperature ranges provides an indication of the composition of the sample, including volatiles and inert filler, as well as indications of thermal stability Test Procedure: Set the inert usually N2 and oxidative O2 gas flow rates to provide the appropriate environments for the test.
Place the test material in the specimen holder and raise the furnace. The gas environment is preselected for either a thermal decomposition inert – nitrogen gasan oxidative decomposition air or oxygenor a thermal-oxidative combination.
