Abstract : This paper presents use of the Depth Profile mode coupled with LA-ICP-MS for analysing ancient gold coins. It explains how this mode can improve the characterisation of coins for the following difficult analytical problems: surface gold enrichment, low fineness gold alloys, localised enrichments in platinum and palladium and inclusions of platinum group elements.
