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.

这个SGER奖授予约翰B教授。弗吉尼亚联邦大学的Fenn得到了化学系分析和表面化学项目的支持。 所提出的工作的主要研究目标是在电喷雾电离作为一种手段，用于采样极性分子夹带在逆流气流的喷雾机制的发展。 PI是了解此类雾化和电喷雾过程的过程和动力学的杰出专家，并且处于开展这项工作的独特位置。 这项SGER赠款将支持开发一种新颖而有见地的喷雾技术。 初步结果表明，这种方法的发展在ppb和ppt检测水平的承诺。
