Raman spectroscopy allows to characterize the molecular structure of various organic and inorganic pigments. This is usually the method of choice for the identification of modern organic pigments.
Infrared Spectrometry (FTIR)
Infrared spectrometry is a technique for molecular analysis which allows to characterize organic materials (binding media, varnishes, adhesives, synthetic fibres etc) and inorganics (pigments, corrosion products, salts etc.). Coupling the spectrometer with a research microscope permits the analysis of microsamples barely visible to the unaided eye.
Gas chromatography – mass spectrometry (GC-MS)
Gas chromatography allows to separate organic mixtures such as oils, synthetic and natural resins, waxes, proteins, plant gums etc., and to characterize individual components. This technique is particularly suitable for studying complex mixtures and degraded organic products.
