Thermogravimetric Analysis

Stress Engineering Services provides Thermogravimetric Analysis (TGA) for thermal analysis of polymers, polymer based composites and elastomers. TGA can be used to determine the kinetics of decomposition of a material, the distillation temperature of a liquid, the effect of aging and medical sterilization, and the effect of prolonged exposure at static temperatures.

It is a valuable technique when used to analyze the organic/inorganic composition of a material. Samples can be as little as 1 mg. TGA testing can occur in various gaseous environments (Nitrogen, Oxygen, Air, etc.). Our expert engineering staff conducts analysis using both standardized and customized methodology.

ASTM E1131: Compositional Analysis via TGA
