Outline of Final Research Achievements

In this study, we established a novel direct measurement method to analyze secondary organic aerosols (SOA) using pulsed glow discharge plasma ionization source for mass spectrometry (MS). The plasma obtained are stable so that soft ionization was achieved high sensitivity by performing pulsed soft plasma ionization (SPI)/MS measurement under pressure of several kPa. The distribution of chemical species in the discharge tube was also examined with a 2D spectrometer. The predominant ionization reactions of sample molecule would undergo adduct ionization by attachment with protons from the water clusters.

Academic Significance and Societal Importance of the Research Achievements

本研究では、直流パルス-ソフトプラズマイオン化質量分析装置(DC-pulsed-SPI/MS)を用いて、SOA生成に寄与するVOCをソフトにイオン化する方法を確立した。この手法はリアルタイム直接分析法を用いた質量分析(DART/MS)と異なり、同軸型電極構造を用いたイオン源であり、それ故、キャリアガスとしてヘリウムでなく、空気を用いることができることから、その場分析技術としての利用が期待される。
