| Research Abstract |
Origin of homochirality of amino acids is one of the most important subjects for origins of life. Recently, it is thought that homochirality was achieved in the space environment. In order to confirm this hypothesis, small amount of enantiomeric ratio of amino acids should be determined in the space samples e.g. cosmic dusts. Therefore, we developed a high sensitive enantiomeric analysis system and demonstrated a analysis of very small particle of carbonaceous chondrite.
