Infrared spectrometry (FTIR)

Infrared spectrometer allows identifying pigments and binding media based on their characteristic infrared spectra.

FTIR analysis characterizes materials, and is especially useful in recognizing inorganic mixtures. FTIR, as well as Raman spectroscopy, can provide the molecular and structural information about organic and inorganic materials. Both techniques allow non-destructive analysis.

FTIR and Raman spectroscopies are considered complementary techniques. Compared with FTIR, Raman is much less sensitive to organic materials, such as varnishes, binders, and some organic pigments.
