Objectif
"As a first approximation, the isotopic compositions of the elements can be considered as constant in nature. However, small variations do occur and isotopic analysis of the elements showing such variations can provide very valuable information in several domains of science, e.g. archaeometry, forensics or environmental research.
Whereas isotope ratio mass spectrometry (IRMS) is traditionally used to investigate the isotopic composition of light elements, for a long time, thermal ionization mass spectrometry (TIMS) was the only technique providing sufficient precision (RSD = 0.005%) to detect slight variations in the isotopic composition of the heavier elements. Nowadays, multi-collector inductively coupled plasma mass spectrometry (MC-ICPMS) is an even more powerful tool for highly precise isotope ratio determination as it provides information on the small variations (often 1‰) shown by some elements that are not or hardly accessible by means of TIMS (e.g. elements with high ionization potential) and, therefore, the importance of MC-ICPMS is currently growing, also in the field of provenance determination.
The main goals of this research project will be the development of analytical methods for measuring the isotopic composition of Cu (colorizer), Sb (decolorizer) and Ti (introduced via sand) in glass and subsequent use of the methods developed for provenance determination of ancient glass objects. First, optimization studies will be performed using conventional solution nebulization as a means of sample introduction. The work will comprise the development of isolation methods for each of the target elements, as well as the validation of the methodology proposed in terms of analyte purity, recovery and absence of fractionation. In a second phase, it will be evaluated whether laser ablation can be used as an alternate method of sample introduction, to render the approach quasi non-destructive, self-evidently an important asset for studying valuable objects."
