Thermogravimetric Analysis (TGA)
In thermogravimetric measurements, a small amount of material is placed into a microbalance pan situated inside a furnace. The material is heated at a constant rate while weight versus temperature is recorded. Analysis is performed to determine volatiles, inorganic fillers, and degradation point; a plot of percent weight versus temperature is also included.
This test can be carried out with nitrogen or air as a purge gas. A switch over temperature from nitrogen to air can also be specified.

Ash Content, Combustible Material, Highly Volatile Matter, Medium Volatile Matter, Percent Weight Loss v. Temperature, Percent Weight Loss v. Time. This data appears in Matereality as Thermogravimetric Analysis.
Number of times this test is repeated: 1
0.1 kg of pellets [details]
This test is used to determine inorganic content, degradation temperature, and residual solvent levels.
