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.

这个项目是在分析和表面化学的一般领域和原子吸收光谱的子领域。首席研究员将通过大气压-温度程序解吸和温度程序静态二次离子质谱法研究材料在加热表面和高温表面反应中的解吸。本研究将有助于了解原子吸收光谱中石墨表面电热雾化的基本方面。该技术广泛用于分析极低含量的金属杂质。
