FTIR collects a spectrum from an analysed area, which can be compared to reference spectra of known materials. It can be used with complementary techniques such as XRF in close range, or VIS-NIR and SWIR reflectance spectral imaging at remote range, for a more comprehensive identification of a material.​

The ISAAC mobile lab is equipped with a suite of FTIR spectrometers that allow both point analysis and mapping at micro and macro-level. Our systems enable the analysis in various modes such as external reflectance, transmission and attenuated total reflectance (ATR), depending on the needs of each project.

Micro FTIR spectroscopy and mapping using the standalone LUMOS II FTIR microscope. Data collection can be performed in various modes (i.e. external reflection, transmission or Attenuated Total Reflection (ATR). As the FTIR spectrometer is integrated, the microscope is easily movable to any location to assist in analysing organic and inorganic materials at the microscale. The extensive working distance allows samples and objects up to about 4 cm thick to be analysed. 

​

The ISAAC lab is also equipped with a commercial small footprint Bruker Alpha 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 mid IR).​​​​
