Proton-transfer-reaction mass spectrometry (PTR-MS) has been widely used to study the emissions, distributions, and chemical evolution of volatile organic compounds (VOCs) in the atmosphere. The applications of PTR-MS have greatly promoted understanding of VOC sources and their roles in air-quality issues. In the past two decades, many new mass spectrometric techniques have been applied in PTR-MS instruments, and the performance of PTR-MS has improved significantly. This Review summarizes these developments and recent applications of PTR-MS in the atmospheric sciences. We discuss the latest instrument development and characterization work on PTR-MS instruments, including the use of time-of-flight mass analyzers and new types of ion guiding interfaces. Here we review what has been learned about the specificity of different product ion signals for important atmospheric VOCs. We present some of the recent highlights of VOC research using PTR-MS including new observations in urban air, biomass-burning plumes, forested regions, oil and natural gas production regions, agricultural facilities, the marine environment, laboratory studies, and indoor air. Finally, we will summarize some further instrument developments that are aimed at improving the sensitivity and specificity of PTR-MS and extending its use to other applications in atmospheric sciences, e.g., aerosol measurements and OH reactivity measurements.

质子转移反应质谱:在大气科学中的应用

质子转移反应质谱法(PTR-MS)已被广泛用于研究大气中挥发性有机化合物(VOC)的排放,分布和化学演化。PTR-MS的应用极大地促进了人们对VOC来源及其在空气质量问题中的作用的了解。在过去的二十年中,许多新的质谱技术已应用于PTR-MS仪器中,并且PTR-MS的性能已得到显着改善。这篇综述总结了PTR-MS在大气科学中的发展和最新应用。我们将讨论PTR-MS仪器的最新仪器开发和表征工作,包括使用飞行时间质量分析仪和新型离子引导界面。在这里,我们回顾了已学到的有关重要大气VOC的不同产物离子信号的特异性的知识。我们介绍了使用PTR-MS进行VOC研究的一些近期亮点,包括在城市空气,燃烧生物的烟羽,森林地区,石油和天然气生产地区,农业设施,海洋环境,实验室研究和室内空气中的新观察结果。最后,我们将总结一些进一步的仪器开发,旨在提高PTR-MS的灵敏度和特异性,并将其应用扩展到大气科学中的其他应用,例如气溶胶测量和OH反应性测量。石油和天然气生产地区,农业设施,海洋环境,实验室研究和室内空气。最后,我们将总结一些进一步的仪器开发,旨在提高PTR-MS的灵敏度和特异性,并将其应用扩展到大气科学中的其他应用,例如气溶胶测量和OH反应性测量。石油和天然气生产地区,农业设施,海洋环境,实验室研究和室内空气。最后,我们将总结一些进一步的仪器开发,旨在提高PTR-MS的灵敏度和特异性,并将其应用扩展到大气科学中的其他应用,例如气溶胶测量和OH反应性测量。
