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.
Portable FTIR spectrometer in external reflection mode (Alpha Bruker) at the Royal Brighton Pavilion
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.
