Fast-(semi)quantitative elemental mapping using state-of-the-art laser ablation-inductively coupled plasma-time of flight-mass spectrometry (LA-ICP-TOF-MS) was applied to a set chondritic meteorite samples.

Optimizing the LA-ICP-MS procedure to obtain 2D and 3D high-resolution multi-elemental imaging of heavily degraded Roman glass for studying weathering mechanisms by monitoring lateral in-depth distribution elements.

Introduction Selenium is an essential element to human health at low levels (2080 μg/L), but becomes toxic at elevated levels. Selenium exists in different forms that determine its toxicity and bioavailability. Current research is now focusing on the determination of individual selenium species or seleniumcontaining compounds. This can be done using ICP-MS as a selenium-specific detector for a ...

Introduction: Zirconium (Zr) and hafnium (Hf) are incompatible, lithophile, and refractory trace elements. In general, trace element distribution and relative abundances may provide very valuable information of geological processes. With respect to meteorites, Zr /Hf ratios may help decipher condensation conditions and sequences during the early stages of solar system formation. With analytical...

This study represents a joint pilot project between archaeological and natural sciences, aimed at exploring the technology and provenance of gold artefacts, exemplified for the case of Georgia. It is focussed on the prehistoric gold mine of Sakdrisi. The study included the investigation of both Bronze Age gold artefacts and native gold by chemical and lead isotope analyses using ICP-mass spectr...
