Development and Application of Photoionization Technology for Organic Analysis of Particulate Matter
Photoionization (PI) is a soft ionization method that does not cause the production of molecular fragments from target materials. Applications of soft photoionization–mass spectrometric methods to molecular analysis are reviewed here. A non-selective photoionization technique (single-photon ionization, SPI) can be used to measure volatile compounds with molecular mass < 120 m/z, while a soft and selective technique (resonance enhanced multi-photon ionization, REMPI) is better suited for aromatic compounds whose molecular mass is > 100 m/z. The development of hyphenated thermal–optical analyzer photo-ionization time-of-flight mass spectrometers (PI-TOFMS) combined with REMPI and SPI methods has enabled the analyses of evolved gaseous species, and these advanced methods have led to new insights into the elemental and organic carbon in particulate matter. Nonetheless, technical developments in the REMPI/SPI–TOFMS framework are far from complete, and there are opportunities for the development of new process analysis applications.
期刊介绍：
ASE is an international journal that publishes high-quality papers, communications, and discussion that advance aerosol science and engineering. Acceptable article forms include original research papers, review articles, letters, commentaries, news and views, research highlights, editorials, correspondence, and new-direction columns. ASE emphasizes the application of aerosol technology to both environmental and technical issues, and it provides a platform not only for basic research but also for industrial interests. We encourage scientists and researchers to submit papers that will advance our knowledge of aerosols and highlight new approaches for aerosol studies and new technologies for pollution control. ASE promotes cutting-edge studies of aerosol science and state-of-art instrumentation, but it is not limited to academic topics and instead aims to bridge the gap between basic science and industrial applications. ASE accepts papers covering a broad range of aerosol-related topics, including aerosol physical and chemical properties, composition, formation, transport and deposition, numerical simulation of air pollution incidents, chemical processes in the atmosphere, aerosol control technologies and industrial applications. In addition, ASE welcomes papers involving new and advanced methods and technologies that focus on aerosol pollution, sampling and analysis, including the invention and development of instrumentation, nanoparticle formation, nano technology, indoor and outdoor air quality monitoring, air pollution control, and air pollution remediation and feasibility assessments.
