Principle
This technique introduces volatile components or decomposition products generated during TGA thermogravimetric analysis into an infrared spectrometer for IR detection, analyzing and identifying the structure of evolved gas components. Meanwhile, at specified temperature points, volatile/decomposition products can be introduced into a chromatograph for separation and identification. It is widely applied in the separation and identification of complex organic components, serving as one of the primary detection methods in analytical chemistry.
