Simultaneous Thermal Analysis (TG-DSC) Service
Simultaneous Thermal Analysis (STA), commonly referred to as TG-DSC, is a sophisticated analytical technique that combines Thermogravimetry (TGA) and Differential Scanning Calorimetry (DSC) to study the thermal properties of materials. This method offers a comprehensive understanding of material behavior under controlled temperature conditions, providing insights into thermal stability, phase transitions, and reaction kinetics.
The underlying principle of Simultaneous Thermal Analysis (TG-DSC) is the simultaneous monitoring of mass changes and energy changes in a sample during a controlled thermal program. This is achieved through the use of a specialized instrument that houses both a thermogravimetric analyzer (TGA) and a differential scanning calorimeter (DSC) within a single, integrated system.
In a typical STA experiment, a small sample (typically a few milligrams) is placed in a sample holder, which is then subjected to a predefined temperature program in a controlled atmosphere (e.g., inert, oxidizing, or reducing). As the sample is heated or cooled, the TGA component continuously measures the change in sample mass, while the DSC component measures the heat flow into or out of the sample.
The TG curve generated by the TGA component provides information about the sample's thermal stability, decomposition kinetics, and weight-related phase changes. The DSC curve, on the other hand, reveals the energy changes associated with physical and chemical transformations, such as melting, crystallization, glass transitions, and various endothermic or exothermic reactions.
By analyzing the combined TG and DSC data, researchers can gain valuable insights into the thermal behavior, phase changes, and chemical reactions of the sample, which is crucial for understanding the performance and suitability of environmentally friendly materials in various applications.
Comprehensive Data:
The simultaneous acquisition of TGA and DSC data provides a more complete understanding of material behavior. By correlating mass changes with heat flow, researchers can distinguish between events that involve mass change and those that do not, such as phase transitions.
Improved Accuracy and Precision:
STA ensures that TGA and DSC measurements are taken under identical conditions, including atmosphere, heating rate, and sample environment. This consistency leads to more accurate and precise data, as external variables are controlled and minimized.
Time and Cost-Efficiency:
By combining two techniques into one, STA saves time and resources compared to running separate TGA and DSC analyses. This efficiency is particularly valuable in research and development where multiple samples need to be tested.
