This Small Business Innovation Research (SBIR) Phase I project addresses the accurate measurement of the composition and microphysics of atmospheric aerosols that have significant implications for global and regulatory environmental issues. This project would replace the quadrupole mass-spectrometer (QMS) with a compact time-of-flight mass spectrometer (TOFMS). This would enable the measurement of complete chemical composition on a particle by particle basis. Key to this is the electronic and data acquisition system, which will make semi-continuous TOFMS practical computationally. The Phase I project will lead to the construction of a prototype instrument that will have unique capabilities for real time monitoring of ambient aerosol chemistry and microphysics. Moreover, the coupling of high efficiency EI to the compact TOFMS will have many other potential mass spectrometric applications.The commercial market for the existing aerosol mass spectrometer includes government and educational research labs, and may expand to include regulatory monitoring efforts and process industrial laboratories.

这个小企业创新研究 (SBIR) 第一阶段项目致力于精确测量大气气溶胶的成分和微物理，这对全球和监管环境问题具有重大影响。该项目将用紧凑型飞行时间质谱仪 (TOFMS) 取代四极杆质谱仪 (QMS)。这将能够在逐个颗粒的基础上测量完整的化学成分。其中的关键是电子和数据采集系统，这将使半连续 TOFMS 在计算上变得实用。第一阶段项目将建造一个原型仪器，该仪器将具有实时监测环境气溶胶化学和微物理的独特功能。此外，高效 EI 与紧凑型 TOFMS 的耦合将具有许多其他潜在的质谱应用。现有气溶胶质谱仪的商业市场包括政府和教育研究实验室，并可能扩展到包括监管监测工作和过程工业实验室。
