Outline of Research at the Start

宇宙空間で脂肪族炭化水素が普遍に分布する証拠は天文学・物質科学の両分野から多数発 見されていることから、脂肪族炭化水素は初期太陽系における有機物進化の前駆物質の一 つであると考えられている。一方で、炭素質隕石から抽出される脂肪族炭化水素はガスクロマトグラフィーでは分離できない複雑な混合物(UCM)として検出されるため、同定が困難であり、30年以上研究が行き詰まっていた。そこで本研究では、地球外起源UCMの構造決定を目的として、炭素質隕石に含まれる脂肪族炭化水素の二次元ガスクロマトグラフィー質量分析を行い、地球外起源であると期待されるUCM炭化水素の分離と同定、そして起源決定に取り組む。

Outline of Final Research Achievements

For the purpose of separating and determining the structures of coeluting compounds of aliphatic hydrocarbons contained in carbonaceous meteoritesIn a preliminary experiment, we analyzed unresolvable complex compounds (UCMs) in terrestrial sediments by two-dimensional gas chromatography time-of-flight mass spectrometry (GCxGC/ToFMS), and succeeded in separating them into about 10,000 peaks. Next, we used two different ionization methods (electron impact ionization (EI) and field ionization (FI)) in a gas chromatography time-of-flight mass spectrometry (GC/ToFMS) for aliphatic hydrocarbons in carbonaceous meteorites, and the FI mode successfully enabled detection of molecular ions of each peak that could not be detected by EI, and it enabled separation of peaks that were not separated by EI.

Academic Significance and Societal Importance of the Research Achievements

従来の分析技術では同定困難な組成不明の複雑炭化水素化合物は、地球外物質のみならず、石油、食品、香気サンプル、環境サンプルなどにも幅広く含まれる。本研究において複雑炭化水素化合物の分離分析手法を発展させたことは、宇宙化学分野をはじめ様々な分野へ貢献できる成果である。
