Analysis of Trace Species in Gases

授予弗吉尼亚联邦大学约翰·B·芬恩教授的SGER奖由化学部的分析和表面化学项目支持。这项工作的主要研究目标是发展电喷雾电离中的喷雾机制，作为一种采样反向流动气流中携带的极性分子的手段。PI在了解这种雾化和电喷过程的过程和动力学方面是杰出的专家，并在开展这项工作方面具有独特的地位。这笔SGER赠款将支持喷雾技术的一项新的和有洞察力的补充的开发。初步结果表明，该方法有望在ppb和ppt检测水平上得到发展。

This SGER award to Professor John B. Fenn of Virginia Commonwealth University is supported by the Analytical and Surface Chemistry Program in the Chemistry Division. The primary research objective of the proposed work is the development of the spray mechanism in electrospray ionization as a means for sampling polar molecules entrained in a counter flowing gas stream. The PI is the pre-eminent expert in the understanding of the processes and dynamics of such nebulization and electrospray processes, and is in a unique position to carry out this work. This SGER grant would support the development of a novel and insightful addition to the spray technology. The preliminary results show promise for development of this method at the ppb and ppt detection level.
