MRI: Acquisition of Instrumentation for Real-Time Molecular Level Measurement of Atmospheric Gas- and Particle-Phase Compounds

空气质量和成分研究，特别是挥发性有机化合物及其氧化产物导致二次气溶胶颗粒形成的研究，是基于对许多化合物的分子特性和浓度的详细了解。考虑到关键化学中间体的复杂性和经常消失的小浓度，优选诸如高分辨率质谱的技术。格鲁吉亚理工学院的一个跨学科小组共同从事大气化学、气溶胶、云、气候和空气质量研究，将获得一种商用仪器，即气体和气溶胶高分辨率飞行时间化学电离质谱仪（FIGAERO-HR-ToF-CIMS）的过滤器入口。该仪器将推进大气痕量气体/气溶胶/云/空气质量的研究，使本科生和研究生接触最先进的质谱技术，并作为增加格鲁吉亚理工学院科学和工程多样性的场所。

Air quality and composition studies, especially of volatile organic compounds, their oxidation products leading to secondary aerosol particle formation, are based on a detailed knowledge of the molecular identity and concentration of many chemical compounds. Given the complexity of, and often vanishingly small concentrations of key chemical intermediates, techniques such as high resolution mass spectrometry are preferred. An interdisciplinary group at Georgia Tech jointly engaged in atmospheric chemistry, aerosols, clouds, climate, and air quality research will acquire a commercial instrument, a Filter Inlet for Gases and AEROsols High Resolution Time-of-Flight Chemical Ionization Mass Spectrometer (FIGAERO-HR-ToF-CIMS). This instrument will advance research in atmospheric trace gases/aerosols/clouds/air quality, expose undergraduate and graduate students to state-of-the-art mass spectrometric techniques, and serve as a locus to increase diversity in science and engineering at Georgia Tech.
