    　View Summary

    <p>Roles of solar energetic particles in habitability of the early Earth and in formation of amino acids and their enantiomeric excesses were examined by simulation experiments. SEPs are mainly composed of high energy protons, and it was suggested that high-flux SEPs were generated from the young Sun and entered into Earth atmosphere. It was shown that such SEPs were major energy to form amino acid precursors, in the case that primitive Earth atmosphere was slightly reducing. SEPs were produced N<sub>2</sub>O, which is greenhouse effect gas and could be keep the early Earth habitable. SEPs could generate spin-polarized muons, which may have formed enantiomeric excesses of amino acids.</p>

  • Evaluation of analytical method of complex organic matter by pyrolysis gas chromatography mass spectrometry for future application to extraterrestrial materials

    Mogi Yuto, Kebukawa Yoko, Kobayashi Kensei

    Abstracts of Annual Meeting of the Geochemical Society of Japan  2020   GEOCHEMICAL SOCIETY OF JAPAN

    　View Summary

    <p>Pyrolysis gas chromatography-mass spectrometry (GC / MS) can reveal more detailed characteristics of the structure of organic matter by changing the pyrolysis temperature. In order to investigate the structure and thermal characteristics of complex organic matter, a method "Continuous" that performs GC / MS analysis at a series of pyrolysis temperatures by repeatedly using the same sample, and a method that prepares a new sample for each pyrolysis temperature "Replaced" step heating methods were examined and evaluated. In addition, Fourier transform infrared spectroscopy (FT-IR) analysis was also performed using a heating stage to observe changes in the sample during analysis.The reproducibility of each of the two methods was confirmed. With the "Replaced" method, it was possible to discriminate fine peaks, and with "Continuous", the difference in the detected compounds was remarkable for each pyrolysis temperature. The results of the experiments using FT-IR were in line with the tendency of the compound species detected at each pyrolysis temperature in the GC / MS experiments. Therefore, it was found that performing pyrolysis GC / MS analysis by changing the pyrolysis temperature using both methods is useful for the analysis of the components and thermal properties of complex organic molecules.</p>
