Introduction:
TGA/DSC is an exceptionally versatile instrument for the characterization of physical and chemical material properties. Thermogravimetry (TGA) is a technique that measures the mass change of the sample when going through thermal processes in a defined atmosphere. The TGA/DSC3+ system equipped with an ultra-micro balance and includes unique built-in calibration ring weights and provides sub-microgram resolution. The system also allow simultaneous measurement of Differential Scanning Calorimetry (DSC) heat flow data beside TGA weight loss data. DSC measures enthalpy changes associated with transitions / reactions and the temperatures allows the instrument to detect thermal events that are not accompanied by a change in mass, such as melting, glass transitions, and solid-solid transitions. Application areas include plastics, elastomers and thermosets, mineral compounds and ceramics.
