Professor Charles L. Wilkins of the University of Arkansas is supported by the Analytical and Surface Chemistry Program in the Division of Chemistry for conducting fundamental studies in polymer mass spectrometry, focusing on the characterization of copolymers. In particular, a combination of high-resolution mass spectrometric techniques will be employed for solving the problem of copolymer sequence determination.Synthetic polymers are an important component of every-day life, and new polymers for tailored applications aimed at improving the quality of life are constantly being developed in academia and industry. To accomplish this goal, methods for the accurate characterization of polymer structures are essential. Mass spectrometry's dispersive nature makes this method ideally suited for the analysis of polymers that are essentially mixtures of molecules of different masses. This work will improve the methods available for polymer analysis, facilitating the development of novel polymers. Besides the potential broader scientific impacts, this work will educate students, including undergraduates and minorities, in the expanding area of mass spectrometry.

阿肯色大学的Charles L. Wilkins教授受到化学系分析和表面化学项目的支持，在聚合物质谱方面进行基础研究，重点是共聚物的表征。特别是，高分辨率质谱技术的组合将用于解决共聚物序列测定的问题。合成聚合物是日常生活的重要组成部分，为提高生活质量而量身定制的新型聚合物正在学术界和工业界不断开发。为了实现这一目标，精确表征聚合物结构的方法是必不可少的。质谱法的色散特性使该方法非常适合于分析本质上是不同质量分子混合物的聚合物。这项工作将改进现有的聚合物分析方法，促进新型聚合物的开发。除了潜在的更广泛的科学影响，这项工作将教育学生，包括本科生和少数民族，在不断扩大的质谱领域。
