TG FT-IR 

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 (FT-IR) 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, with the exception of homonuclear diatomics and noble gases, a characteristic spectrum for each substance.
