项目摘要

The present proposal describes follow-up work as a continuation of the very successful joint effort of the three research groups Analytical, Physical and Theoretical Chemistry of the University Wuppertal, and the Institute of Jet Propulsion and Turbomachinery of the RWTH Aachen University. The work performed over the past three years, funded by the DFG, resulted in a number of major achievements with regard to a more fundamental understanding and deterministic development of atmospheric pressure ionization (API) sources. A pivotal role played high-quality computational fluid dynamics simulations, which were successfully used as input parameters for ion trajectory calculations. A couple of new generation API sources already operational are used in e.g. the analysis of polycyclic aromatic hydrocarbons. The main goal of the present proposal is a rigorous continuation, application, and extrapolation of the data and knowledge base assembled in the preceding three years. The present joint research efforts will focus on the development and analytical application of laminar low-flow and actively controlled high-flow API sources. These two novel designs were identified as the most powerful API source types. Preliminary sources at the initial design stage have already proven to be clearly superior to commercially available conventional API sources with regard to sensitivity, stability, and temporal resolution.

本提案将后续工作描述为延续了三个研究小组的联合努力，分析了Wuppertal大学的分析，物理和理论化学，以及RWTH AACHEN大学的JET推进和涡轮机械研究所。在过去三年中，由DFG资助的工作在大气压力电离（API）来源的基本理解和确定性发展方面取得了许多重大成就。关键作用起着高质量的计算流体动力学模拟，成功用作离子轨迹计算的输入参数。在例如多环芳烃的分析。本提案的主要目标是在前三年中组装的数据和知识库的严格延续，应用和外推。目前的联合研究工作将集中于层流低流量和积极控制的高流量API来源的开发和分析应用。这两个新型设计被确定为最强大的API源类型。在初始设计阶段的初步来源已经被证明在敏感性，稳定性和时间分辨率方面显然优于市售的常规API来源。
