We perform molecular analysis with an Agilent 4300 Handheld FTIR spectrometer. This system allows to analyze art and archaeology directly on their surface without any damage or sampling. This method requires a special probe and it is called FTIR Diffuse Reflectance Spectroscopy. The results can be considerably different from standard FTIR spectroscopy and, consequently, it … Continue reading CHSOS Application note # 2: FTIR Diffuse Reflectance. Pigments Checker Database
