“…In the work of Finkeldei and Staats, it was shown that P had been overestimated previously in many steel reference standard materials. 118 (The same holds true for the determination of P and 13 other trace elements in cement. 119 ) In the work of Traub et al 120 different calibration strategies for the determination of trace elements in pure copper metal by nanosecond laserablation ICP-MS were investigated.…”

ICP-MS is based on the formation of (preferentially monovalent positively) charged atomic ions in an inductively coupled Ar plasma at almost 10 000 K. The ions formed are transferred from the plasma source at ambient pressure into a mass separator operated at high vacuum via a set of cones. The ions are separated according to their mass/charge ratio in the mass separator (quadrupole, magnetic sector field or time-of-flight mass separator). In most cases, the ions are detected using a secondary electron multiplier; in some set-ups (also) a Faraday cup can be used. Single-collector (scanning mass spectrometer usually used for quantitative elemental analysis) or multicollector (static operation of mass spectrometer for precise isotope ratio analysis) configurations can be found (Figures 12.1 and 12.2).

“…Inductively coupled plasma mass spectrometry (ICP-MS) was then utilized to obtain the elemental composition of the watchcases. ICP-MS has been used to analyse jewellery [4,5] as well as to determine the trace-metal composition of steel [6]. Table 1 summarizes the major and minor elements that were quantified.…”

Counterfeit watches are products of illicit activity and contain traces of their production and distribution. Traces provide pertinent information through one of their fundamental characteristics: the ability to reveal links between specimens or cases. The aim of this study was to develop an analytical strategy to obtain the elemental composition of watchcases, by analysing a selection of 35 counterfeit watches. We propose a methodology based on multivariate statistical analysis of chemical results that discriminates between watches from common and different origins, and, ultimately, classifies them into chemical groups. All watchcases were analysed using inductively coupled plasma mass spectrometry (ICP-MS), providing representative descriptive data on the composition of watchcases. Several multivariate approaches were assessed, considering different scenarios, each using a different set of variables. It appeared that the model that performed best in terms of classification criteria could be misleading, especially in an exploratory context that focuses on the production of intelligence. At the end of the day, hierarchical cluster analysis (HCA) allowed us to classify the specimens into 14 chemical classes. Information gained through chemical analysis revealed several links between the specimens. This initial study was performed on a very limited number of watches. Although still in the developmental stage, our approach exhibits promising capabilities and encourages chemical profiling of counterfeit watches on larger scale.
