External reflection Fourier Transform Infrared (FTIR) spectroscopy

ISAAC lab is equipped with a commercial small footprint FTIR spectrometer that can be operated in external reflection mode thus enabling non-invasive and non-destructive measurements of FTIR spectra in a large spectral range (from short wave IR to midIR).  


  • Identification of organic and inorganic materials;

  • Assistance of pigments and binding media  identification;

  • Analysis of degradation products.

External reflection Fourier Transform Infrared (FTIR) scanning

Our FTIR mapping system is an in-house developed system that interfaces a portable external reflection FTIR with an X-Y-Z motorised translation stage (max. area 15x15 cm2) that automatically scans and produces a FTIR spectral image cube with scanning speed up to ~0.1 mm/s limited by the FTIR sensitivity.
