Electrothermal Atomization and Surface Chemistry

该项目属于分析和表面化学的一般领域，以及原子吸收光谱分析的子领域。主要研究人员将通过大气压-程序升温脱附和程序升温静态二次离子质谱仪研究加热表面物质的脱附和高温表面反应。这项研究将有助于理解原子吸收光谱中使用的石墨表面电热雾化的基本方面。这项技术被广泛用于分析极低水平的金属杂质。

This project is in the general area of analytical and surface chemistry and in the subfield of atomic absorption spectroscopy. The principal investigator will study desorption of materials from heated surfaces and high temperature surface reactions by means of atmospheric pressure-temperature programmed desorption and temperature programmed static secondary ion mass spectrometry. This research will aid in understanding fundamental aspects of electrothermal atomization on graphite surfaces used in atomic absortion spectroscopy. This technique is widely used for the analysis of extremely low levels of metal impurities.
