Synchronous thermal analyzer is an important material science research tool, which can provide thermogravimetric (TG) and differential heat (DSC) information at the same time, and is of great significance for material science research and development. This paper will introduce the basic principle, work flow of synchronous thermal analyzer and its significance and function in practical application.

The basic principle of synchronous thermal analyzer is based on the combination of thermogravimetric and differential thermal analysis techniques. Thermogravimetric analysis is an analytical technique to measure the relationship between sample mass change and temperature, which can study the thermal stability and decomposition behavior of the sample. Differential thermal analysis (DTA) is an analytical technique to measure the relationship between the temperature difference and time between the sample and the reference material, which can study the phase transition and reaction heat of the sample. The simultaneous thermal analyzer combines these two analysis techniques to obtain thermogravimetric and differential thermal information of a sample in the same measurement, giving a more complete understanding of the thermal properties of the sample.

The work flow of synchronous thermal analyzer includes the steps of preparation before experiment, operation and data processing during experiment. Before the experiment, it is necessary to select the appropriate crucible, sample and experimental conditions, put the sample into the crucible, and then place the crucible in the instrument for measurement. During the experiment, the instrument records the weight changes and temperature changes of the sample and transmits these data to a computer for processing and analysis. Data processing includes drawing thermogravimetric curve and differential thermal curve, calculating the thermal properties of the sample, etc.

Synchronous thermal analyzer has a wide range of meanings and functions in practical applications. It can help scientists better understand the thermal and chemical properties of materials, thus providing an important reference for the development and application of materials. For example, in the study of the synthesis and processing of polymer materials, the synchronous thermal analyzer can be used to study the melting, crystallization, oxidation and other behaviors of materials, so as to guide the preparation and processing of materials. In addition, synchronous thermal analyzer can also be widely used in drug research and development, ceramic materials and other fields.
