Thermogravimetric analysis (TGA) is one of the members of the family of thermal analysis techniques used to characterize a wide variety of materials. TGA provides complimentary and supplementary characterization information to the most commonly used thermal technique, Differential Scanning Calorimetry (DSC). PerkinElmer offers a variety of high performance TGA instruments encompassing a wide range of application needs and operational requirements. The extended capabilities of the PerkinElmer TGA, as a valuable tool for polymeric characterization and quality assurance are demonstrated by these applications.
