Outline of Final Research Achievements

For the comprehensive and simultaneous observation of volatile organic compounds (VOCs), a new ultra-high resolution mass spectrometer, in which a soft-ionization technique (proton-transfer reaction (PTR) ionization) and an ultra-high resolution mass spectrometer (multi-turn time-of-flight mass spectrometer: MULTUM) are combined as PTR-MULTUM, was developed. As the first step, laboratory-based PTR-MULTUM with an ordinary size of differential pumping system was developed, which has ion guide and ion accumulation system for better detection sensitivity. It had a detection limit of 32 ppbv (xylene, 1000 data accumulation in 20 sec) and mass resolution of 24200. A field-deployable smaller size of PTR-MULTUM was then developed and basic functional check had been completed.

Academic Significance and Societal Importance of the Research Achievements

揮発性有機化合物(VOCs)は,地球的な環境問題となっているPM2.5やオキシダントの原因物質であるが,ごくわずかしか同定されていない.本研究で開発したPTR-MULTUMは,従来の分析法では測定できていない未同定VOCsなども含めて,VOCsを一括して直接測定するために必要な,高い質量分解能を持っていることが示されており,更なる小型化や高感度を進めることで,VOCsの一括直接網羅分析が可能となると期待され,PM2.5・オキダントといった環境問題解決の重要なVOCs分析ツールとなると期待される.
