FT-IR, thermogravimetric


Thermogravimetric analysis (TG) follows changes in mass of the sample as a function of temperature and/or time. TG gives characteristic information about the composition of the measured sample, the amounts of the various components and their thermal behavior. In addition, further measurements are possible such as kinetic analysis of thermal decomposition. The identification of gases released directly from the sample or during thermal treatment cannot be performed just by thermal analysis but coupling a spectroscopic method such as Fourier-Transform-Infrared (FTIR) spectroscopy is an excellent solution. IR spectroscopy is a classical technique, which depends upon the interaction of infrared radiation with the vibrating dipole moments of molecules. It gives, except for homonuclear diatomics and noble gases, a characteristic spectrum for each substance. This combination yields a powerful analytical technique that combines the quantitative capabilities of TG and the qualitative capabilities of FTIR spectroscopy. TG-FTIR is useful for a wide range of applications, including: • Outgasing of Materials • Detection of Residues • Analysis of Additives • Analysis of Aging Processes • Competitive Analysis • Characterization of Natural and Raw Materials • Desorption Behaviour • Analysis of Synthesis Processes • Analysis of Decomposition Processes
