Outline of Annual Research Achievements

本研究では、地球外起源のUnresolved Complex Mixture（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）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（GCxGC）質量分析を行い、共溶出化合物の分離・同定を行うことを目的としている。当該年度は、小惑星探査計画「はやぶさ2」で帰還した小惑星リュウグウサンプルの初期分析および成果発表を最優先する必要があったため、当該研究を十分に進めることができなかったが、試料の前処理は前年度に完了している。

Current Status of Research Progress

4: Progress in research has been delayed.

Reason

当該年度は、研究代表者がはやぶさ２初期分析固体有機物チームのリーダーとしての任務に専心する必要があったため、個人の研究としての本研究課題の進捗は遅れている。

Strategy for Future Research Activity

試料の抽出は完了したので、次年度は二次元ガスクロマトグラフィー質量分析測定を行う。

Causes of Carryover

当該年度は、研究代表者がはやぶさ２初期分析固体有機物チームのリーダーとしての任務に専心する必要があったため、個人の研究としての本研究課題の進捗は遅れ、次年度使用額が生じた。
今後、抽出試料の二次元ガスクロマトグラフィー質量分析測定を行う。
