The transitions between the vibrational energetic states of atoms represent the infrared absorption spectra, which is a band spectrum over which the transitions between energetic rotational states overlap. One of the most important uses of infrared absorption spectrometry is the identification in quantitative terms of the structure of compounds from a substance, the analytes being either solid, liquid or vaporous. The FTIR-TGA Coupling is a technique that permanently controls the mass loss in a sample, as a function of temperature and time, as well as the identification and recording of various compounds occurring during the combustion process. Research on hydraulic oils has consisted of their analysis using the FTIR-TGA coupling in order to identify flammable substances that can generate explosive events.
