Current evaluation of powder geological samples elemental analysis using laser-ablation inductively coupled plasma mass-spectrometry

摘要

Laser-ablation inductively coupled mass-spectrometry (LA-ICP-MS) has been widely used for elemental measurements of geological samples and other solids for many years. Its particular interest in geology has been usually focused on spatial resolution trace-element determinations of different mineral phases or analysis of fluid inclusions. The bulk elemental analysis of geological materials with LA-ICP-MS is not so spread because it meets several serious restrictions e.g. homogeneity of samples and absence of matrix-matching standards.
