  • Abstract “Aerosols”, suspensions of ultrafine particulates in a gas, play significant roles
    in a number of important research fields, including the atmospheric chemistry, planetary sciences, environmental sciences as well as the biomedical sciences and therapeutic administration. Since aerosols have various size, shape, composition and architecture, it is crucial to understand the fundamental physical, chemical and optical properties of aerosols from the atomic and molecular level. In order to address these issues, we have recently constructed a novel multi-functional aerosol instrument. This new multi-functional aerosol instrument is composed of three main parts, including (I) a long- path, temperature adjustable aerosol chamber coupled with the rapid-scan Fourier transform infrared spectrometer, (II) an adjustable aerodynamic lens system to produce a focused and size-selected aerosol particle beam, and (III) an aerosol ultraviolet photoelectron spectrometer (UPS) chamber with a high-resolution hemispherical electron energy analyzer. Aerosols are generated either by an atomizer or formed in-situ in the long-path aerosol chamber under well-controlled conditions. The aerosol size distribution and concentration are characterized via a scanning mobility particle sizer (SMPS). The performance of this newly developed aerosol instrument and some preliminary results of each part will be discussed.
