Solving the plasma analyte interaction problem: Toward a fundamental advancement in plasma-assisted microanalysis and materials characterization

等离子体构成了许多当今领先的微量分析和材料表征分析方法的中心组成部分。在所有这些方法中，等离子体-分析物相互作用直接关系到最终的分析物响应，尽管这些相互作用的确切性质是复杂的，并且在很大程度上没有很好地理解，限制了方法的精密度和准确性。这些问题的核心仍然是分析物汽化、解离和电离的物理学，以及热和质量传递过程，以及光学方案的相关发射过程。研究小组已经认识到，整个血浆分析物相互作用的问题是真正跨部门的分析社区，作为回应，制定了一个综合的计划，以全面的解决方案。拟议的研究旨在将基本的等离子体分析物测量和标准开发与理论框架和综合建模工作相结合，以实现基于等离子体和等离子体辅助分析方法准确性的范式改变，这对于支持微分析，纳米科学，新材料开发和生物科学等更大的研究工作是必要的。

Plasmas form the central component of many of today’s leading analytical methods for microanalysis and materials characterization. In all of these methods, the plasma-analyte interactions are directly related to the ultimate analyte response, although the exact nature of these interactions is complex and for the most part not well understood and limit the method precision and accuracy. At the core of these issues remains the physics of analyte vaporization, dissociation and ionization, as well as heat and mass transport processes, and relevant emission processes for optical based schemes. The research team has recognized that the overall plasma-analyte interaction problem is genuinely cross-cutting over key sectors of the analytical community, and in response has formulated an integrated plan toward a comprehensive solution. The proposed research seeks to combine fundamental plasma-analyte measurements and standards development with a theoretical framework & comprehensive modeling effort to bring about a paradigm change in the accuracy of plasma-based and plasma-assisted analytical methods that is necessary to support, for example, larger research efforts in microanalysis, the nanosciences, novel materials development, and the biosciences.
