X-Ray Fluorescence Analysis of Valuable Metals

“…Owing to these facts, the peak area vs concentration -the relationship I M = f(c M ), M being the metal to be determined-cannot be used and, consequently, neither the methods based on it. With the aim of minimizing this problem, Sándor et al have developed methods to overcome the effect of geometrical dissimilarity [33,34]. Other authors rotate the objects in order to compensate for the irregularities that may occur [35,36].…”

X‐ray fluorescence analysis on a group of coins from the ancient roman city of Tridentum (Trento, Italy)

“…[1] A number of papers have been published in recent years, devoted to the nondestructive analysis of Greek silver coins, [2] Roman bronze [3][4][5] and silver coins, [6][7][8][9][10] silver and golden medieval coins, [11][12][13] and other coinages. [14][15][16] The aim of the analysis is, in general, the determination of the composition of the coins, with the purpose of understanding the practices of coinage and the materials used.…”

“…The archaeometric analysis of ancient coins gives important information about the economic and social organization of the society in which they were used . A number of papers have been published in recent years, devoted to the nondestructive analysis of Greek silver coins, Roman bronze and silver coins, silver and golden medieval coins, and other coinages …”

Quantitative analysis of ancient Chinese ceramic using k 0-instrumental neutron activation analysis

“…NAA is a technique, which is considered the most reliable analytical tool for the determination of trace elements for provenance studies of prehistoric ceramic objects [7][8][9]. It has been employed for many decades in the analysis of ancient objects such as coins [10,11], pottery and ceramic artefacts [12]. No other technique offers such a high level of sensitivity and accuracy as provided by NAA [13].…”
