Differential Scanning Calorimetry (DSC) is the most-employed Thermal Analysis method. NETZSCH offers a variety of DSC instruments, accessories and services designed to meet your analytical needs across various industries.Differential thermal analysis (DTA) is a thermoanalytic technique that is similar to differential scanning calorimetry. In DTA, the material under study and an inert reference are made to undergo identical thermal cycles, (i.e., same cooling or heating programme) while recording any temperature difference between sample and reference. This differential temperature is then plotted against time, or against temperature (DTA curve, or thermogram). Changes in the sampl.

2. Differential Thermal Analysis (DTA) • Principle: The basic principle involved in DTA is the temperature difference (∆T) between the test sample and an inert reference sample under controlled and identical conditions of heating or cooling is recorded continuously as a function of temperature or time, thus the heat absorbed or emitted by a chemical system is . Figure \(\PageIndex{1}\): Illustration showing typical experimental curves for a differential thermal analysis (DTA) or a differential scanning calorimetry analysis (DSC) for a polymeric material. For a DTA analysis, the difference in temperature, \(\Delta T\), is measured and for a DSC analysis, the flow of heat is measured.A differential thermal analyzer, also commonly referred to as a DTA analyzer, is used in analytical chemistry to identify and quantitatively analyze the chemical compositions of a sample by heating the sample and recording the behavior of the sample, which includes the temperature and heat flow between phase transition (i.e. melting point, crystallization, etc.) as a sample will . DTA is a thermal analysis which involves the comparison between the temperatures of sample under investigation and a thermally inert material/reference which may be α-alumina (it is densified alumina in α-phase and occurs in hexagonal structures) and this comparison is then recorded with the furnace temperature as the sample is heated or cooled .
TGA/DSC, or Thermal Gravimetric Analysis/Differential Scanning Calorimetry, is an important technique used in material characterization. It is commonly used in research and extensively in the polymer, chemical, battery, renewable energy, pharmaceutical, and food industries.

The thermogravimetric and differential thermal analysis of the compound under study is performed to determine the temperature of sublimation and thermal events such as melting. Figure \(\PageIndex{17}\) shows a typical TG/DTA plot for a gallium chalcogenide cubane compound (Figure \(\PageIndex{18}\) ).Recently, with the development of the highly-functional polymeric material, these thermal properties analysis needs are increasing dramatically. DTA and DSC detect the temperature differences between the sample and the reference; however, DSC can perform the quantitative measurement of the amount of heat on top.Differential thermal analysis (DTA) is a widely used method for analyzing materials. DTA utilizes the fact of a characteristic energy conversion during the phase transition for qualitative and quantitative analysis. The measurement is based on a comparison of the sample temperatures with a reference.
