Researchers find TGA method useful for quality control of graphene powders

A research collaboration between The University of Adelaide in Australia and the National Physical Laboratory has led to the development of a validated analytical tool, thermogravimetric analysis (TGA), for the characterization and quality control of FLG and non-graphene impurities in powder form. TGA is typically used to assess and characterize the thermal properties and impurities of minerals, polymers, and carbon materials. However, its was found to have potential for use as a characterization tool for regulating the quality of graphene materials.

Now, this affordable, simple and reliable method of analysis could be used to improve the quality control measures used in the graphene industry.
