A comparative analysis of five chrome green pigments based on different spectroscopic

A detailed study of five chrome-based green pigments belonging to a large pigment collection at the Academy of Fine Arts in Vienna, Austria has been performed. The samples were analyzed and compared using the two X-ray methods— X-ray fluorescence and X-ray diffraction, and the two optical methods— Raman spectroscopy and infrared spectroscopy. The composition differences between the similarly denoted samples of the collection were determined and the significant sensitivity differences of the investigated methods to specific compounds have been established. This relative discrepancy of the obtained results depending on the technique used proved once again the need of a combined use of the investigated methods.
