A glow discharge optical emission spectrometer for challenging surfaces

该项目旨在通过实施辉光发射光谱仪来解决澳大利亚研究中一个关键的表面表征差距。确定粗糙、易碎和空气敏感的化学复杂表面的成分深度剖面是非常具有挑战性的。该项目将允许对表层进行快速、准确的元素深度分析，厚度可达数百微米，分辨率可达纳米级。关键的是，该仪器允许手套箱到仪器的分析，而不需要表面制备，保留表面的原位状态。这将加快电池材料的研究，控制腐蚀的新方法，以及先进工程表面的设计。

This project aims to address a critical surface characterisation gap in Australian research by the implementation of a glow-discharge optical emission spectrometer. Determining the composition depth profile of chemically complex surfaces that are rough, fragile, and air-sensitive is very challenging. The project will allow rapid and accurate elemental depth profiling of surface layers up to hundreds of microns in thickness and with nanometre resolution. Critically this instrument allows glovebox-to-instrument analysis without surface preparation, preserving the in-situ state of the surface. This will fast-track research in battery materials, new methods to control corrosion, and the design of advanced engineered surfaces.
