Description

This Master Prompt provides a comprehensive framework for determining what a material is chemically composed of, where its constituent elements are located, how composition varies across phases, interfaces and microstructural regions, and what chemical or electronic states exist at surfaces and near-surface regions. It encompasses local and bulk elemental analysis, surface-sensitive characterization, quantitative compositional analysis and spatial chemical mapping using techniques represented across the uploaded literature, including EDS/EDX, wavelength-dispersive approaches, XRF, XPS, ICP-based methods, mass spectrometric techniques, LIBS, EPMA, NAA, elemental mapping and complementary microanalytical methods.
