There is a great variety of the art expertise objects. Among them are paintings, sculpture, applied art pieces, old weapon, furniture and cloths, coins and stamps, cards and photos, old books and manuscripts, and so on

X-ray fluorescence method is often used for art expertise being unique rapid and nondestructive method at a time. XRFA determines the main composition of the sample as well as small additives.
Presence of some element in the analyzed object may indicate its adulteration, or incorrect determination of the object origin. A good instance is the study of the old paintings – XRFA determines the element composition of the paint and therefore determines the pigments of the paint, which were typically used in a definite period of time.

The same approach is used for metal objects analysis based on Fe, Cu, Ag, Au (coins, statues, silverware, metal threads, Etruscan gold). Each period of time had corresponding technology of metal production which influenced the metal composition and typical admixtures.

Adulteration may be determined at the qualitative analysis stage due to presence of typical additive elements in spectra. The quantitative analysis is fulfilled with fundamental parameters method. Samples of any shape can be analyzed,  the only limit is the sample holder size.
