Thermal Analysis provides ideal tools für the characterization of organic and inorganic, either solids or liquids. Thermodynamic transitions, thermal stability, decomposition and chemical reactions can be detected and quantified with high accuracy over a broad temperature range   
   
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, with the exception of 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 identification capabilities of FTIR spectroscopy. 
 
Three modes of connecting the FTIR to TG: 
 

Coupling to an external gascell via transfer line for highest FTIR system flexibility. 
 

Coupling to an internal gascell via transfer line using the FTIR sample chamber.
