PAPER – QUANTITATIVE COMPOSITIONAL MAPPING

by | 20 Jul 2020 | Publications

We have published in collaboration with Francesca Picolli from the group Metamorphic Geochemistry a paper in IOP Conf. Series: Materials Science and Engineering outlines some important aspects of analytical procedure for quantitative compositional mapping by electron probe micro-analysis (EPMA) and laser ablation inductively-coupled plasma mass spectrometry (LA-ICP-MS) along with recommended instrument operating conditions. Several artefacts affecting the maps are also discussed.

Illustration of possible electron-specimen interaction in two rock-forming minerals covering the high spectrum of mean atomic number (Z) and density (ρ). Possible effects of the pixel size (dx) on the spatial resolution of X-ray maps is discussed in this paper. Image modified from Lanari & Picolli (2020).
