MRI: Development of a Controllable optical emission spectroscopy diagnostic system for use in atomic and molecular sciences

这个奖项是根据2009年美国复苏和再投资法案(公法111-5)资助的。在这个项目中，申请者提出了一种新的化学分析技术的开发。化学物种的分析对许多技术进步都很重要。目前的技术依赖于吸附光谱、电感耦合等离子体原子发射光谱(ICP-AES)、质谱仪(MS)、气相色谱(GC)和其他一些诊断方法。根据行业的不同，通常有一种工具被认为是标准工具。例如，环保局根据在系统内使用电感耦合等离子体发射光谱工具的GC工具的能力来制定污染标准。PI建议完成一种新诊断系统的基本开发，该系统有可能取代电感耦合等离子体原子发射光谱仪，从而彻底改变发射光谱研究以及GC系统的能力。具体地说，新工具是基于使用具有良好特性的可变电子束来产生发射。通过使用可变的电子源，电子的密度也可以独立于电子能量而被控制。这一变化允许开发一种新的发射光谱分析工具，这些工具价格低廉，易于校准，并允许直接测量密度。

Analysis of chemical species has been important to many technological advances. Current technologies rely on adsorption spectroscopy, inductively coupled plasma-atomic emission spectroscopy (ICP-AES), mass spectrometry (MS), gas chromatography (GC) and a few other diagnostics. Depending on the industry, there is often one tool that is considered the standard. For example the EPA sets pollution standards based on the capability of GC tools which employ ICP-AES tools within the system. The PI proposes to complete the basic development of a new diagnostic system that has the potential to replace ICP-AES and thus revolutionize both emission spectroscopy studies as well the capabilities of GC systems. Specifically the new tool is based on the use of well characterized variable electron beams to produce the emission. By employing a variable electron source, the density of the electrons can also be controlled independent of the electron energy. This change allows the development of a new class of emission spectroscopy tools that are inexpensive, easy to calibrate and allow direct density measurements.
