Fourier transform infrared spectroscop

Fourier Transform Infrared Spectroscopy (FTIR) is a gas analysis method that allows analysis of gases with respect to their composition.

The analyser passes mid-infrared wavelength radiation through gas samples and measures the absorption. Quantification of gases is performed with respect to specific peaks on the IR absorption spectrum and correlated with a known database of chemical compositions.

The FTIR is connected by a heated transfer line to the Simultaneous Thermal Analysis instrument (STA6000). The testing procedure typically requires a small sample of material to be gradually heated in the STA. The gasses released by the samples are then collected and passed through the FTIR analyser. This allows the key parameters of the material to be quantified and the degradation of a material with temperature to be understood.
