Termogravimetrialla

Termogravimetrialla is a thermoanalytical technique used to measure changes in a material's mass as a function of temperature or time in a controlled atmosphere. The technique involves placing a sample on a sensitive balance within a furnace. As the temperature is increased or held constant, any mass loss or gain due to decomposition, dehydration, oxidation, or other chemical reactions is continuously recorded. The resulting data is plotted as a thermogravimetric curve, with mass change on the y-axis and temperature or time on the x-axis.

Key information obtained from a thermogravimetric analysis includes the temperatures at which mass changes occur, the extent of mass loss or gain, and the number of distinct decomposition steps. This data can be used to determine the thermal stability of materials, identify volatile components, study reaction kinetics, and assess the composition of a sample. Applications are widespread across various scientific and industrial fields, including polymer science, pharmaceuticals, ceramics, metallurgy, and environmental analysis. For example, it is used to study the degradation of plastics, the drying of active pharmaceutical ingredients, or the composition of inorganic compounds.
