Differential Scanning Calorimeters (DSC) is a powerful analytical tool for the identification of various physical properties and thermal transitions of polymeric materials. It measures the energy transferred to or from a sample undergoing a physical or chemical change. Common usage includes investigation, selection, comparison, and end-use performance evaluation of materials in research, quality control and production applications.
TGA is a powerful technique for the measurement of thermal stability of materials including polymers. In this method, changes in the weight of a specimen are measured while its temperature is being increased. Moisture and volatile contents of a sample can be measured by TGA. Thermogravimetric data is critical to setting proper temperature limits for Differential Scanning Calorimetry method development.
