These two Perkin Elmer Pyris instruments work in conjunction. Thermal analysis examines the behavior of materials as they are heated in a controlled stepwise manner. TGA tracks the mass of the sample as volatile components are released, while DSC measures the thermal energy absorbed by the material.
Applications:
- confirmation of the identity of synthetic polymers such as mylar and polyester
- revealing the presence of plasticizers and other contaminants in polymers
- determination of the glass transition temperature of adhesives
