What is thermogravimetric analysis?

Thermogravimetric analysis is a technique used in science and industry to describe how a solid sample changes as it heats up gradually Samples may change due to water loss, changes in crystal structure, or molecular changes due to decomposition This analysis is used to describe polymer and coal samples, as well as dated plots and other uses The sample analysis is carried out in a controlled environment, and the sample is continuously weighed during heating An inert gas may be introduced to avoid oxidation during heating The output consists of temperature curve and weight loss curve When presented in different forms, the slope of the curve changes to a peak value, making it easier for scientists to identify sample switching points The weight analysis or final quantity analysis is determined by the weighing sample, which is usually a very accurate analysis technology Thermogravimetric analysis, on the other hand, is more like a descriptive technique The peak value can be measured at the time of energy release or sample structure transformation In some hydrogenated molecules, the peak occurs at the time of heat removal hydration The amount of heat needed to cause this change is also a measure of the strength of the bond between molecules and water Polymers are often described by thermogravimetric analysis Scientists observed softening and degradation points and evaluated fusion analysis and filler composition Flame retardant materials can be measured in this way to evaluate the conditions under which combustion occurs Organic materials such as coal can also be described by thermogravimetry This technology has replaced a variety of tests of the valuation coal needed between buyers and sellers This method can evaluate the moisture content, volatile matter, fixed carbon and ash of coal Some kinetic studies, or the determination of reaction rates, are done by thermogravimetric analysis These studies are sometimes carried out by continuously analyzing the gases released when the sample is heated Kinetic studies determine the order of the reactions, which means how many molecular species must be mixed at each stage of the reaction Thermogravimetric analysis is also useful in forensic chemistry This technique can describe varnishes and paints By comparing known samples, you can determine the age of a particular artwork In addition, the tool can be used to find useful information about the stability of drugs.
