Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market asym the world.

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.

A plot of percent weight loss versus temperature. Thermogravimetric analysis uses heat to force reactions and physical changes in materials.

TGA records change in mass from dehydration, decomposition, and oxidation of a sample with time and temperature.

Standards can be obtained from appropriate standard authorities. Global Reach Intertek is the industry leader with over atm, people in 1, locations in over countries.

Assurance Testing Inspection Certification. Set the inert usually N2 and oxidative O2 gas flow rates to provide the appropriate environments for the test.

Compositional Analysis by Thermogravimetric Analysis (TGA)

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: Send us a request Wilton UK: Thermogravimetric TGA analysis provides determination of endotherms, exotherms, weight loss on heating, cooling, and more.

Materials analyzed by TGA include polymers, plastics, composites, laminates, adhesives, food, coatings, pharmaceuticals, organic materials, rubber, petroleum, chemicals, explosives and biological samples. Certification Aatm confirming that your products and services meet all trusted external and internal standards.
