Fundamental Studies of Inductively Coupled Plasmas Using Power Modulation and Chemical Relaxation Techniques

这项研究是在分析化学和表面化学的一般领域和原子光谱学的子领域。本研究的目的是阐明导致电感耦合等离子体（icp）发光的过程。本研究的基本假设是ICP是一个动态系统，似乎是受动力学控制的。本研究旨在研究ICP的时间依赖过程，包括电离、重组和激发。这将通过调制输送到等离子体的功率来实现。这种方法将允许研究等离子体中激发态和离子的时空响应。这项研究的目的是为了更好地理解在被称为等离子体的特殊高温光源中导致光发射的过程。总体目标是使用这个特殊的源提供更好的元素分析。

This research is in the general area of analytical and surface chemistry and in the subfield of atomic spectroscopy. The goal of this research is to elucidate the processes which lead to emission of light from inductively coupled plasmas (ICPs). The fundamental hypothesis of this research is that the ICP is a dynamic system which appears to be kinetically controlled. This research is designed to study the time-dependent processes of ICP including ionization, recombination, and excitation. This will be accomplished by modulating the power delivered to the plasma. Such an approach will allow studies of the spatial and temporal response of excited and ionic species in the plasma. This research is designed to better understand the processes which lead to emission of light in special high temperature sources called plasmas. The overall goal is to provide better elemental analysis using this special source.
