“…A mountable laser cell developed by EMPA, which also allows direct mounting of the cell on larger objects, was used for all the LA-ICP-MS analyses. The cell design is an advanced prototype of the mountable cell reported by Devos et al (1999).…”

Ten Early Bronze Age (BzA1, 2200-2000 BC) copper artefacts from the central Valais region from Switzerland were studied for their elemental composition and lead isotope ratios. In order to answer the archaeological question of a local copper supply, a database for copper minerals across the Valais (Switzerland) has been established. This database contains 69 data on lead isotope ratios as well as additional information on the minerals and geochemical associations for copper minerals from 38 locations in the Valais. Comparisons of the artefacts were also made with data pertaining to minerals from various deposits from Europe and Anatolia taken from the literature. The provenance of the materials is very diverse. Some of the data are compatible with the data from the copper mineral deposits of the Valais region. Moreover, three copper lunulae were identified as possibly Tuscan, which demonstrates contacts between Italy and the Valais region. This pattern also establishes a multiplicity of provenances for the metal and cultural influences in the Alpine environment of the Rhone Valley of Switzerland at the beginning of the Early Bronze Age.

“…Using LA/ICPMS, visible damage can be restricted to an acceptable minimum. Such studies were reported by Devos et al,112 in which a specially designed sample chamber was used, and almost invisible 100-µm craters were produced on antique silver objects. The elements Zn, Cd, Sn, Sb, Au, Pb, and Bi were measured, and their contents were used to distinguish forgery in silver antiques.…”

Laser ablation (LA) is a unique technique to transform a solid sample into vapor‐phase constituents, which then can be chemically analyzed by atomic spectroscopy. Ablation brings many exciting capabilities to the field of chemical analysis, primarily because of the laser‐beam properties. The ability to analyze directly any solid samplewithout sample preparation and minimal sample‐quantity requirements are just some of the unique capabilities. This article discusses current issues related to using LA in atomic spectroscopy. A general introduction to LA sampling is presented along with a comparison with other solid sampling techniques. The critical issues for all analytical techniques are calibration, accuracy, and sensitivity. Techniques that have been demonstrated to address these analytical characteristics and define these parameters for LA are investigated in detail. Finally, many unique applications are described, ranging from dating geological materials to providing crime‐scene evidence. Most of these applications could not be performed without the use of a laser beam. The inductively coupled plasma (ICP) will be emphasized in this article because it is currently the most prevalent excitation and ionization source for chemical analysis using LA.

“…Especially coins are objects of great historical value and x-ray based techniques can provide a proper determination of their manufacturing technology, age, authenticity and give useful information about the monetary history of a certain period (Rodrigues 2011). Pd and Cd are both archeologically relevant elements, Cd being particularly important for authenticity verification of silver antiques since it is being used as an additive in silver solders and alloys only recently and its presence clearly indicates a fairly modern origin of a silver alloy sample (Devos 1999).…”
