STTR: Aerosol Mass Spectrometer for Size and Composition Analysis of Sub-Micron Size Particles

小行星9523186 本研究旨在发展一种气溶胶质谱仪，以分析大气中亚微米级粒子的粒径和成分。该设备的技术将建立在气溶胶采样和质谱分析的成熟技术的组合，以开发一种基于尺寸选定的亚微米颗粒的热线蒸发的颗粒成分分析的新方法。 该光谱仪将能够同时确定各种气溶胶颗粒的化学成分，而无需使用昂贵而精密的激光系统。 这种光谱仪的成功开发将比目前正在开发的大多数竞争系统更具成本效益，并将在各种各样的现场应用中发挥作用。 这些应用包括环境气溶胶监测，实验室气溶胶物理学，以及气溶胶形成和增长机制的其他研究。

9523186 Jayne This research is to develop an aerosol mass spectrometer for size and composition analysis of sub-micron size particles in the atmosphere. The technology for this device will build on a combination of proven technology for both aerosol sampling and mass spectrometry to develop a novel approach to particle composition analysis based on hot wire vaporization of size selected submicron particles. This spectrometer will have the ability to determine the simultaneous chemical composition of the full range of aerosol particles, without the use of expensive and delicate laser systems. The successful development of this spectrometer will be more cost effective than most competing systems now under development and will be useful in a wide variety of field applications. These applications include environmental aerosol monitoring, laboratory aerosol physics, and other studies of aerosol formation and growth mechanics.
