How to choose the right thermogravimetric analyzer

Thermogravimetric analyzer (TGA) is a kind of instrument used to detect the relationship between temperature and mass of a substance. Thermogravimetry is to measure the mass of a substance with temperature (or time) under programmed temperature control. When the substance under test sublimates, vaporizes, breaks down gas or loses crystal water during heating, the mass of the substance under test will change. In this case, the thermogravimetric curve is not a straight line but a decline. By analyzing the thermogravimetric [...]

Understand the characteristics of the differential thermal analyzer

Differential thermal analyzer is a technique to measure the temperature difference and temperature relationship between a substance and a reference substance under programmed temperature control. The DTA curve describes the temperature (△T) between the sample and the reference material as a function of temperature or time. As a classical thermal analysis method of thermal effect under controlled program temperature, it has been widely used in the research and development, process optimization, quality control and failure analysis of various materials [...]

The use of differential thermal analyzer tips together to understand the next

The principle of the differential thermal analyzer is: the sample to be tested and the reference substance (thermal inert substance) are placed in the furnace under the same conditions, and the temperature is heated or cooled at the same speed according to the given program. When the heated sample produces changes in physical and chemical properties at different temperatures (such as phase transformation, crystallization structure transformation, crystallization, boiling, sublimation, gasification, melting, dehydration, decomposition, oxidation, reduction… And other reactions), accompanied [...]
